Someone who is so far in last, they think they're in first. A play on car races, where the last guy appears to be in first but in actuality is doing an absolutely horrific job.
How's Ted doing these days?
He's so far in last he thinks he's in first. A true backside leader. He's delusional.
To break wind, let go of brown air, etc.
-Oops, sorry, I just made an backside air. Keep moving.
-Jesus man! What did you eat yesterday?!

When you're doing a chick from behind right before you cum you spit on her back.. and when she turns her head to look at you you blow your load in her face.
I was doing her from behind and doubled up on the backside fakey and angry pirate.

Its when a girl's ass grows one nipple on each cheek so that her ass cheeks become a pair of titties and since ass cheeks are usually bigger than titties, the titties on the girl's ass are said to be busty.
I like it when a girl has a busty backside because then a girl has four titties and thats twice as good as two.
