When a super hot chick bites the longest part of your beard/goatee and gives it a little tug and shake.
Roy: "She billy-goated me"
Brian: "She just clapped on and shocked you like a rag-doll?"
Roy: "Yeah dude, weirdest and sexiest thing ever. You need to grow yours out."
Troll killer, one who thwarts or denies the trolling attempts of new users on message boards, in Irc channels, or anywhere else trolls are likely to congregate. See "The Three Billy Goats Gruff."
When a man is performing the sexual act of "tittyfucking" by putting his penis inbetween her breasts and then thrusting. When the man is about to ejaculate he makes sure that it he shoots his load onto the womans chin. Which will give her a white goatee like she is a billy goat
Jan loved it when i gave her the Billy Goat because she is an avid animal lover

A male Cougar... A man who is seven years old than the woman he is with and/or dating he is a Billy Goat(Male version of a Cougar)
A person overzealous about taking out trolls, to the point that nearly no one can discuss a subject with varying points of view because the least criticism, controversial statement, or personal opinion is viewed as trolling.
I was banned from an ethics discussion board because a billy goat who resented my views reported me to an admin.

Just prior to a woman performing felatio, you shave your testicular region and keep the shavings in your clenched fist. Upon fruition, the male makes his deposit on his victims chin, then immediately throws the hair in his fist on to the lucky ladie's face. The hair that remains will form a lovely Billy goatbeard on her chin.
