Sub-tweeting is the act of tweeting about somebody without actually saying its about them..
So sub-bitching is bitching about someone, trying to make it more generalized even though its clearly aimed at one person
For example;
Roqueesha: "Some people really don't know how to do their make-up."

Lily: "Is she talking bout me??"

Breezy: "Yeah she's clearly sub-bitching"

Get the Sub-bitching mug.
A group of females between the ages of 18-27 riding together the metro/subway/T-line/bus, etc.

Usually rated as 10's in body and 1 in brains, can be seen ranting about moronic issues, mocking other people's clothing, and minding what's none of their businesses in a very loudly way, as if they owned the transporting device.

Paradoxically, this strange behavior still unknown to common sense, disappears when they ride alone. They become very shy, insecure and autistic characters, but nonetheless in some unexpected situations well rounded 10's with over a 4 of brains can be found acting in a normal and polite way.
SB1: -Look at him, he's reading, something...
SB2: -yeah, is he dead?
Guy reading the newspaper: "wtf? ohh, SBs... "

SB1: -That skirt looks slutty in her don't you think?
SB2: -Yeah, and is so "out" wearing that now.
CSW(cute smart woman): -Ohh, that's the girl that my BF left for being a dumb slut, poor thing.

Drunk guy: -Damn Sub-Bitches!!!!!!
