Poobsh 

A person who gets great pleasure in delivering a silent fart

Whilst travelling in the escalator I could smell something horrible - it has to be a 'Poobsh'

This phrase is often used sarcastically. It probably is something.

Probably my Biceps 

pronoun- antecedent is always "biceps"
Expression used for the sake of being used; has lost most of original meaning
Origin- Speculated to have been coined by Theodore Roosevelt, as he was known to have an extremely well developed upper body.

"Knock Knock"
"Who's there?"
"Probably my biceps"
*swooning and possible copulation ensues*

Probally 

Hey, congratulations! You spelled probably wrong. But that's okay, the correct spelling is P R O B A B L Y. If you are having a hard time remembering it, I remember words in chunks. Probably is pro and bably in my brain.

"That's probally true."
"Hey, did you just spell probably wrong?"

"Yeah, stupid autocorrect."
What do you mean? We are having this conversation in person!"

SUB-PROBE 

When your car is such a piece of crap that the value is lower then the value of any Ford Probe.

Dude, your Fiero is Sub-Probe. It literally worth less then $50 bucks.
