A sexual act involving peanut butter, and bird seed.
You pack your butt with a mixture of peanut butter and bird seed and then bend over and hold open your butt cheeks in a place where birds like to go. This allows birds to eat out your ass and feels really good.

a person who is like family but not blood related, someone who you are so close with you basically are family, a family friend.. it saves alot of time instead of having to explain that your not really realated but just very close
your moms best freind from high school you see every weekend is like your costco aunt or if you have someone you see alot around your age but your not that close they are your costco cousin you would say "this weekend im going to me my costco cousin" instead of "this weekend im going to visit this girl whos like my cousin but not really were just very close"

A warehouse where all the fobs shop. Merchandise are usually bulked in large amounts. There is an abundant amount of samples where you can note that a large percentage are not serious shoppers and just "sample".
"Hey, have you noticed that at least every aisle has at least one fob?"
"Really?...oh yea."

Noun - A place where stingy people go and buy their stuff in bulk. Most people end up throwing most of the stuff away anyways. Costco is usually really expensive compared to other places such as Wal-Mart or e-Bay.
A 42" inch plasma is on sale at costco for $1,799! Wait a second, the same TV is going for $1,499 @ wal-mart!
