tumblesalt

The tumblesalt is an acrobatic feat in which a person tucks in mid-air and moves the feet over the head. The tumblesalt can be performed either forwards, backwards, or sideways and is similar to a flip (or, if performed backwards, backflip).

Jane performed a perfect tumblesalt to win the competition.

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."
