Be bent on doing something

Context #1:

Jean: Phillip! I'm so tired! Can't we finish tomorrow? The project isn't due until 5 pm. We have plenty of time in the morning. Let's go to sleep!

Phillip: No way, Jean. I told myself we'd finish this by tonight and we're not going to bed until we do. Sorry!

Jean: You're being really selfish, you know. You're so bent on finishing this project but you're not considering any one else's feelings. I'm tempted to just let you finish it on your own.

Context #2:

Mother: Son, why are your grades so low in your science class this semester?

Son: I don't know mom. I work really hard but the teacher is bent on making my life miserable. She hates me.

Mother: Why do you think that? I'm sure it's not true.

Son: It's true. She doesn't treat me the same as others.

Mother: I'll have to go and talk to her then.

Son: NO! Don't do that. It's really OK!

Explanation: 

To be bent on doing something means that you are obsessed with doing something and you MUST do it.

In example 1, Phillip MUST finish his project, even if it means that Jean and he will lose sleep. 

In example 2, the son claims that his teacher is obsessed with making his life difficult. 

Be sure to change the be verb to match your tense and always use an ing-verb following on

She is bent on preparing all of the appetizers by herself. She won't consider a caterer. 

Mr. Lee has been bent on learning English in less than two years. He studies every single day. 

When I was a kid, I was bent on reading all of the Harry Potter books.

Munchies

Context #1 – Hanging out at home

Jo: Hurry up, the movie is starting.

Becky: I’m trying to hurry, but there’s nothing to snack on and I have the munchies.

Jo: You’re always hungry. Can’t you watch without food?

Becky: Movies are so much better with a snack to munch on.

Jo: I guess. In that case, maybe we should go buy snacks before the movie starts.

Context #2 – Taking a road trip

Charlie: Do you mind making a stop in the next gas station?  We’ve been driving for some time now and I’m starting to get the munchies.

Ana:  No problem. I’m getting hungry too.

Charlie: Do you think we should grab some food first then?

Ana: The next restaurant is way too far from our next stop, so I think snacks will have to do.  We’ll have to better prepare next time. It’s always easy to get the munchies while driving.

The “Munchies” means hunger. Usually for non nutritious foods, like fast food, pastries, snack (junk) foods, etc. Munchies can also be used as a noun to represent snacks (e.g. I need to get some munchies for later).

Marc: Okay, but next time, you have to let me pay.

Context #2 – Paying for the taxi

Vivian: It’s great to see you again. I ordered us a taxi.

Roy: How much was it? I want to cover for it.

Vivian: We never said we would go Dutch. You can pay the next taxi.

Roy: Okay, sure. But for dinner, we will go Dutch. The restaurant we’re going to is not cheap.

To “go Dutch” means to pay for one self. For example, if friends go out to dinner or planned activity, each person will pay for their own food, transportation, etc.
