Semtex Shit 

The act of taking a shit so hard that it sticks to the toilet bowl similar to the way semtex sticks to surfaces/people in the Call Of Duty series.

Sometimes it even has the ability to withstand the force of a flush or two.

Person 1: "Yo man, I just took one hell of a shit, it's stuck on like semtex and it won't flush away, what should I do?"

Person 2: "Oh you took a semtex shit? Its cool, just leave it for the cleaner, I'm sure she won't mind."

*Later that day....*

Cleaner: "WHYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY?!?!"

Semtex 

A word describing the act of “microdosing” MDMA by dipping your finger into the powder, licking it and then flushing it down with large quantities of wine or beer. You should repeat this process 4-5 times in one evening. It was named in Prague, Czech Republic and its name Semtex is related to this origin (Semtex-An explosive from the Czech Republic)

Dude, Laura destroyed her phone when she was leaving the bar yesterday.
How? Was she drunk?
Nah worse, she did Semtex
