One step down from the word
X-treme.
It's commonly known that doing
anything to the extreme is cool and all but only without the "E" at the start does something become so far out it's not
even funny.
"
Hey, check this out, I was walking down the street and then jumped off the kerb...to the extreme!"
"psht, I jumped off a kerb last week to the
X-Treme, that's right, no "
E" at the start!"
"Holy shit, you're my hero, can I have your babies?"
"No, your uterus couldn't handle my
X-TREME sperm."
"ok"
