Tweeps are tweens or teens that hang out with adults 25 years or older on a regular basis. For the adult, this should be a little creepy, since most people their age would like to hang out and party with real adults. Tweeps usually result in tweeping and the adult usually becomes a tweeper.
EX1: Hey Jordan, wanna catch a movie?

That's alright, I've already seen it with my tweeps.

EX2: Hey Jordan, wanna go bowling with Kevin & Hailey?

I would, but I'm tweeping tonight at Keisha's house.

A plaintive cry, usually on twitter: so a cross between tweet and weep.
"tweep," occasionally "tweep!" usually used alone.

"tweep!" is preferred when wanting to express angst and etc further, awaiting kind inquiries.
