moon bounce 

the act of pulling down one's pants far enough to view the crack of the rear (and sometimes the ass floss, also known as a thong ) while jumping on a trampoline.

"yo, stop doing the moon bounce, your ass floss is clearly visible"

Moon Rocks 

Large shards of pure (or almost pure) MDMA. Way better than your average stepped on and super cut bag of powdered molly or pressed ecstasy pills. Taken orally mostly at music festivals, moon rocks are highly potent and will give you a clean long lasting high.

Hope you're wearing your astronaut suit to this Phish festie cuz I got us a big bag of moon rocks.

Allowing a greezy shit to dry on your taint and while having sex dusting shit flakes on your partners head from above.
