cari istilah yang lo mau, kaya' eiffel tower:
The act of a man using his penis to penetrate another mans anus in a dodgy style so that there semen tanks slap together. Hence, 'slapping tanks'.
Bob and George have been togther for 6 years now. Not my idea of fun mind, not really one for tank slapping.
