Salted- Kinda like dissed- for example if you get proven wrong, or someone makes fun of you, you are salted. You can also be mad salted. There is also the spanish equivalent, that sounds like salow! but of course I couldn't spell it if my life depended on it.
Sauced- Like salted but not as cool.
No homo- If you tell a friend of the same sex you like his/her outfit, hair, phone, piercing,or weave- you have to add no homo, man, no homo.
Thirst- You want it really bad. Teachers are often thirst when they ask students to take off their hats and tuck in their shirts. You can also be mad thirst.
Forcin' it- This is used to describe situations where people are being ridiculous. If a teacher asks a student to actually do schoolwork, they are forcin' it. When someone insists they are right, they are forcin' it. You can also say "that's a force" in reference to a situation.
Lean- This term also involves hand motions. First, you give a friend the "come here" sign with your hand. When they lean in, you say "lean" in a loudish, quick type voice, and at the same time, hit the side/back of their head. This is very funny and can be done at any time, especially when someone is being stupid.
