Puppy love (used as a noun)

First Example:

            Tom: Chris said your son is dating?

            Carol: That's what he's telling everyone.

            Tom: I thought he was only 13!

            Carol: He is. It's only puppy love. But he and his girlfriend are so cute together.

            Tom: I remember my first girlfriend. We were both 12, and her name was... actually, I don't remember her name.

            Carol: Don't tell my son that. He told me he's going to marry this girl one day.

Meaning: The expression "puppy love" refers to the strong feelings at the beginning of a relationship, often used for young people and implying that the relationship won't last. Here, Carol says that her 13-year-old son's relationship is only "puppy love," which Tom seems to agree with when he can't remember the name of his girlfriend when he was 12.

Second Example:

            Sheila met her husband in high school; they were both only 17. Their parents and friends said it was just puppy love, and that they'd never last. But they got married 3 years later, and they have been happily married for 20 years now.

Meaning: The expression "puppy love" is also often used in this context, referring to relationships that started at a young age but developed into something long term.

To have the hots for someone (used as a verb)

First Example:

            Sandra: Have you seen the new Calculus professor, Mr. Crow? He's really handsome.

            Patty: Oh my gosh! You have the hots for teacher!

            Sandra: I do not! I was just surprised that he's so young, and kinda cute.

            Patty: (sarcastically) Sure, I believe you. Did you check if he has a wedding ring?

            Sandra: No! I would never date my teacher.

            Patty: Whatever you say...

Meaning: The expression "to have the hots for" someone means to be strongly attracted to someone. The idiom is most often used by another person, often in a teasing manner as in the example here. Here, Patty jokes that Sandra "has the hots for" the new professor after Sandra comments on the teacher being handsome. (usage note: when using this idiom to discuss a teacher, no article is used, presumably due to the 1980s Van Halen song "Hot For Teacher")

Second Example:

            Kevin: Are you going to Tina's party this weekend?

            Jeff: Maybe. Why do you ask?

            Kevin: Well, we all know you've had the hots for her since High school.

            Jeff: What makes you say that?

            Kevin: I just always thought you had a crush on her but didn't do anything because she was dating Michael. Now that they've broken up...

            Jeff: No, I do not have the hots for Tina. She's just a friend.

Scarf Down

Context #1: 

The most embarrassing thing happened to me yesterday at lunch. My problems started in the morning. I forgot to set my alarm and woke up late, so had to rush out of the house without breakfast. By lunchtime, I was so hungry! I scarfed down my lunch like I hadn't eaten in days! The embarrassing part was that my very cute coworker saw the whole thing and I didn't notice until I was finished! Now he probably thinks I always eat like an animal. So embarrassing. 

Context #2: 

This week's party will include a formal dinner. Please use appropriate language. Please do not scarf down your food and don't forget to put your napkins in your laps.

Explanation:

to scarf down something means to eat something very quickly without regard for manners. When using this expression, a noun or name of food should follow the expression. 

He scarfed down the whole bag of potato chips by himself.

Don't scarf down your dinner. You'll upset your stomach. 

In Example 1, the speaker is recalling the embarrassing experience of being extremely hungry and so eating her food so quickly and ravenously. At lunchtime, she didn't care how she ate, or how she looked while she ate because she was very hungry. Only after, she realized that someone else had witnessed her wild eating.

In Example 2, the speaker is giving instructions for the upcoming party. Since the dinner will be formal, participants are instructed to eat slowly and politely, NOT to scarf down their food.
