TYB

Short for "that's your boyfriend." Said to another person after sighting a particularly horrifying-looking male.

(Some meathead walks by wearing a "No Fat Chicks" t-shirt, black socks, shorts, and a backwards baseball cap.)
Bonnie: "Hey Katie - TYB!"
Katie: "Shut up! Is not!"

TYB

Tender young bitch. used to describe a sensitive male friend, a male with no backbone, a male who gets bent over repeatedly and takes it with a smile, a female that looks ready to get down, a female referenced in male conversations when the subject is on sex.

What a fucking TYB!
Seriously man, stop acting like a TYB and stand up for yourself.

tyb

tyb is an acronym for "tell your boys." It is commonly said in response to witnessing something spectacular, noteworthy, or unprecedented that your buddies would be interested in knowing. Most often, the said buddies are absent, but that is not a requirement for saying "tyb" in its correct context.

#1 "Dude, lebron just facialized the whole Pistons team with that monster dunk."
#2 "oh shit! tyb!"

#1 "Took down this dime piece last night. S-M-O-K-E"
#2 "Oh, whattup! tyb!"
