backsack

The part of a man no one should ever have to see. More specifically, the back of a man's scrotum.

Dude, when I was in the locker room today I totally saw some old guy's wrinkly backsack.

backstroke for days

A reference to "Free! Eternal Summer", the sequel to " Free! Iwatobi Swim Club" Where when advertising the swim club, Makoto Tachibana announces when introducing himself, ( he is clearly nervous), that he " Has backstroke for days! And traps just as long". It became a meme for the fujoshi's who watch it.

Me: Makoto has backstroke for days, especially for Haru.
Other person: to bad Haru belongs to Rin
Me: FIGHT ME MAKOHARU FTW KYS RINHARU!

Italian Backstache

A rare medical condition in which the sufferer's back is engulfed in a thick, black, musky muff of hair. Usually those afflicted happen to be extremely short and tend to remain virgins well into their forty's. Sometimes affects the torso and genitals, in these cases the condition is referred to as an "Italian Bodystache".

When Tom removed his shirt revealing his Italian Backstache at the community pool, Jefferson grabbed his son and ran fearing a grizzly attack.

Lisa: "Gena, did you hook up with that guy with the green lantern tattoo last night?"
Gena: "I was going to until he took of his shirt. He had a major Italian Bodystache."
