To have sex with someone.

'Unofficially' going steady with someone. Dating without the boy/girlfriend 'label'.
Is sometimes used to describe a relationship where individuals are having casual sex and are not actually 'item'.

The sadness of not seeing someone for a couple weeks. It could even be a couple days/hours/seconds. You make plans but they never actually happen lol.

To hit someone from the front really hard and cool in a football game. This kind of hit always gets the crowd and teammates going. It is very manly and awesome.

To expose someone’s sexual orientation or gender identity without their consent; usually in the sense of the person “coming out” or revealing they are transgender or of a non heterosexual orientation

to do stuff with someone, without wanting a real relationship with them

I know I never answered your question yesterday about "what your definition of falling for someone is". I didn't answer because I really wanted to think about what my answer would be, so I did. I believe that falling for someone is when you're always thinking about that person, when you could be in a bad mood but once you go hang out with that person you get very happy and forget about what happened before that. I also think that for you to fall for someone that you would have to be able to really understand or predict how someone would feel in a certain situation. But what I think is the biggest part of falling for someone is that when you do end up falling for someone that they become one of your favorite people in the world and dream of being together in the future
