An ass so phenomenal it stops traffic, turns heads, and makes you lose track of time. Often associated with the unfair and unmitigated power of yoga pants. Power is equal too and sometimes greater than hypnoboobs.
Yo Rob man! It's your turn at the weights!!

Sorry I was distracted by that girl on the treadmill with the hypnobooty!!
