1.
An abbreviation for the word probably used to convey the meaning of the words "yeah right."

A sarcastic probably to be used in a situation of doubt.

Can be associated with a silent hand signal involving the index and middle finger put up together on one hand out of sight of the person being "prolled" but not out of sight of those who are in the know.
Guy1: I am so cool, I drank 30 beers last night.
Guy2: Prol.

Guy1: (talking about how much he likes flowers)
Guy2: Yeah, I love flowers too. (throws up silent prol hand signal to buddies in room to signify the oposite and mock guy1)
