ICarlyisms

iCarlyisms are words or phrases that are used to replace slang/swear words on iCarly)

The "Ushe"
The "ushe" (short for "the usual") is a bet that Sam and Freddie made in iFence.

It was a bet in which Sam had to finish reading the book, The Penny Treasure, in one week, and if she did succeed, then Freddie had to stick a garden hose down his pants with the water turned on to make it look like he peed his pants, and if Sam didn't read the book in one week, she had to put the hose down her pants.

Carly doesn't seem to like this bet, probably because she's seen it before, had to do it before, or is the one who has to clean up afterwards (or just because she doesn't like Sam and Freddie's bets). Freddie loses the bet at the end of the episode and pays the "ushe."

Note: This is spelled in closed captions as the yoozh.

"Shoosh Yeah"
Shoosh Yeah is an expression most commonly used by Sam. The phrase is said to show excitement or an agreement of something.
