back in my day 

The way an old man tells you to stop whining about shit that people back in their day did differently

Old Man: Back in my day, we didnt have toilet paper, we just wiped our asses with leaves

Young Man: Holy Shit, that must've sucked ass.

Back Sweat 

The horrible perspiration that comes from prolonged trips in a car. The back sweat is the worst and most nerve-racking part about going on a date, because when you go to hug your date, you pray to God that she doesn't feel the damp rag that is the back of your shirt. Most prominent in summer. Cure-unknown

Well, she dumped me. Probably because I had horrible back sweat after driving all the way to her house!

Back in a jizzy 

A measure of time one is likely to be away from a task at hand, equal to that commonly allocated to the act of masturbating

Luke: Where are you going?
Ryan: I'm off to some guy's place from craigslist to j/o in his model train room, I'll be back in a jizzy.
Luke: Can you bring back some crab meat?
Ryan: Is imitation ok?
Luke: Fo shizzle!

back sweat 

A man's worse nightmare. While frequent in driving, it can often occurs spontaeously when temperatures are above 58 degrees Fahrenheit. Basically from March to October you pray that no girl accidently brushes against your back and feels your moist lumbar. Likewise wearing t-shirts that clearly show your back sweat is also not advised.

"Hey man it's suppose to reach 60 today!"
"Oh crap man, back sweat is coming, i can feel it."

Back to school 

The most hated word! A word that every single kid is terrified off!

Jamie went to the store to get some good! Jamie also realized the {back to school} sign was up

Jamie ran.

Back Crash 

Alternate word for fart. Typical characteristics include a loud, ripping, crackly sound quickly followed by a foul odor.

This girl was giving me a rim job when I let loose with the ultimate back crash...

back yourself 

To have self-belief or confidence in one's self.

Most commonly used in Australians.

Boy 1: "I don't know if Ashley will like me though, she's way too beautiful!"

Boy 2: "Back yourself James, you're a good guy!"
