Backblast Area Clear 

a. a military cautionary statement, when one is firing the AT-4. One looks behind them, scanning for personnel 100 meters back in a 90 degree cone, once it is clear they yell backblast area clear and fire.

a. READY, BACKBLAST AREA CLEAR, FIRE FIRE FIRE

b. Hey Tom, backblast area clear, RIPPPPPP HAHAHAHA

The Backblast

When your doing a girl doggystyle and pull out to cum on her back, you slap her shoulders with both hands as hard as you can and yell BOOOM!!

I gave my girlfriend the backblast last night and she couldn't move for a whole hour!

Butthole backblast 

When you’re eating out someone’s ass from behind, and they let one rip in your face, sending small bits of poop onto your cheeks.

I was eating my girl out last night, I guess she had Taco Bell cause she hit me with butthole backblast.

karmic backlash

When things go smoothly for a period of time and you're enjoying life, karma finds its way back to you and fucks things up.

I had the best November but I'm getting karmic backlash and December is turning out to be such a drag.

study backlash 

That headache you get after the exam when you suddenly stop cramming and your brain just melts to mush.

I had study backlash after cramming at the last minute for my sex ed test.
I got all the answers wrong anyway, making all that cramming a huge waste of time.
