look up any word, like bangarang:
The white pearly secretion ejaculated from a penis onto the tongue of a woman. When it clumps together in pearls of jizz it resembles Tapioca, Hence Testicle Tapioca.
Guy 1: Dude I nutted on this bitches tongue last night!

Guy 2: How'd she like it?

Guy 1: She enjoyed the Testicle Tapioca
