rind toss
The act of throwing or 'humming around' a fruit, preferably an orange, grapefruit, or tangerine with your friends, comrades, or fraternity brothers. When the rind toss is commenced, the citrus fruit will be firm but toward the end it will feel like a soft, juicy titty. The rind toss is over when the fruit explodes in someone's face. Can be performed inside or out doors.
Will: anyone keen for a good ol' rind toss after dinner?

Justin: Sure! let's hum it around later.

Ben: I hope I don't get exploded in the face again!
