Uncle Zack

Noun: Any person(s) who occupy the bathroom for an extended period of time while you are defecating.

An Uncle Zack will usually enter the bathroom, be silent, and usually look in the mirror for extended periods. Be careful not to get caught peeking to see if the Uncle Zack has left.

I was done pinching my loaf but couldn't wipe because there was an Uncle Zack in the bathroom.

Zack

A guy who uses his friends to snoop through other people’s things and also acts fake toward his friends. Nowadays we call people like this snakes, so it’s similar to that.

I got Zacked today by my friend going through all my social media without my knowledge because he didn’t want to ask me himself.

zack and jack

Two guys that happen to be best friends but are complete opposites, only date hoes and act like mild fuckboys but claim they are not. They break girls hearts and are over them the next day. They throw around the word "love" and bring a rubber whenever they see a good ass. They are commonly popular, because people think they are funny. Names are also replaceable with other fuckboy and basic white boy names

" Did you hear Zack and Jack eiffel towered (enter slutty name) last night? Wait, isn't Zack dating (enter slutty name)? yep."
