Backdoor Surprise Edit Meaning

1.

v./n. inf(!) to unexpectedly penetrate someone's anus; often, of a heterosexual couple engaged in doggy style intercourse, when the male withdraws from the vagina, and hilariously re-inserts into the anus without prior warning.

NOT to be confused with the equally amusing Cadbury Surprise.
