Back Flush

Mostly used in the fag community, it is where two men touch their penises together so the pee holes line up and the fore skin is pulled together ( best with one uncircumcised penis and one circumcised ) Then they piss inside of each other's pee hole thus back flushing the penis.

Hey bro, you wanna back flush each other tonight after dinner.

Back Door Fuck

A coward who will surprise attack you from behind and fuck you in the ass, literally and figuratively because they’re too scared to face you upfront.

My boss is such a BACK DOOR FUCK! He keeps telling me one thing and then does the exact opposite. Then “I” end up getting fucked!

back hole of a heart

The backhole of a heart is a large, valveless vein (aka the superior vena cava or SVC) that conveys deoxygenated blood from the upper half of the body and returns it to the right atrium. The SVC may experience a breakphase where the heart quiets down in order to expell any excess waste. This waste makes the back hole very slippery, thus making it perfect for heartanal.

"I feel like the back hole of my heart was about to burst last night... he was just so big..."

"..um, what is the back hole of a heart?"

"oh you poor thing.. you've been missing out! I can ask my friend, he'll show you. ehehe."
"uhh alright i guess?"
