Backside Fakey

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.

backside 

skatebaord terminology - to turn, more specifically, in the direction where after 90 degrees of spinning you are facing backwards, hence, backside.

also refers to the direction you are facing when approaching an obstacle. for example, if you roll up to a curb and it's behind you, any grind that you do on the curb without 180ing into it will be backside (including noseslides and boardslides...)

bs 180 ollies are fun, espesially if you do a sort of 45 to late 135.. its cool.
