Trying to see how many things you can stack on a girl after you’ve knocked her out and before she wakes up and everything falls off her

A common term used to describe a friend. Most commonly used in Southern USA, it used as a term of endearment for a friend. Synonym of: Bucko, Bucket, Scurvy Dog.

Just something cool to call someone, its like old timey cowboy speak.

1) A cowboy. The word is an anglicized version of the Spanish "vaquero", which means someone who does something with cattle.
2) A noticeably masculine man.

Money, money, and more money! It's a slang term, however, for the word "buck" when people try to get cheap and fancy.

a male bonding pastime, involing a sexual act, usually in a hotel room.
A bloke brings a bird back to a shag, before doing this he tips his mates off and gives them a key to the room where he plans to take her. All his mates hide in the room in various places such as wardrobes, behind curtains and in cupboards etc. everyone stays deadly silent when the couple enter the room, the couple begin sex (preferably doggy) then all the blokes jump out and shout buckaroo! the aim of the game is to see how long the bloke can stay on for before the girl freaks out. jumping out naked is not approved as it can be misconstrued as attempted gang rape!
