The inspiration for your jacking off
To what/whom you've been masturbating

You were my jackspiration in high school.

Kelsey's my jackspiration.

backspiration 

Sweat from the back region, particularly the small of the back, that turns your shirt game upside down. Grey t-shirts are particular harbingers of backspiration. The hotter and more humid it is, the bigger the backspiration stain. Sigh.

“Oh man, sometimes I hate walking around the city in the summer. It’s like backspiration central.”

Backspiration 

Backspiration is when someone sweats profusely from his/her back causing a big wet mark. Backspiration is an undesirable occurrence unless actively trying to ward off members of the opposite sex.

Normally I’m super embarrassed by my backspiration, but it sure does help keep Joe, that creep from accounting, at bay.

A source of inspiration, but to Jerk off.

"Dude I was going through Megans Facebook photos yesterday"
"Yeah man, those photos are great for jerkspiration!"
