A word used popularly in Philadelphia, Pa to describe female dogs who get “smutted” around by a group of men. The men are either friends, cousins or even siblings maybe complete strangers but that's rare with Tweaks. Tweakers are often exposed on the Tweaker List page via Facebook. Tweakers are not aware that they’re tweakers, until they appear on the Tweaker List. However, 99.9% are still in denial after being featured on every list. You can always find a Tweaker on Broad & Olney, King of Prussia, and Franklin Mills. They're in there like swimwear.
Girl: I'm not a tweak, I'm 15 years old and I let 5 guys hit.
I only sucked 14 dicks this year. Yes, I'm on the tweaker page, but these girls just hating on me because I had sexual intercourse with their boyfriends.

Boy: Your the true definition of a tweaker.

The word "tweaker" is often used to describe a girl with sloppy, slut-like attributes, and is known for getting with a lot of guys. A tweak is a nicer way of calling a female a whore, and or slut, and a tweaker may get with more popular, or famous guys. The word "tweak" is also used and is just a shorter version of the word "tweaker".
