swah-hee-lee-an bak-slap When receiving oral while standing, right before
ejaculating,
the person receiving oral defecates on their hand, and proceeds to slap it
on the back of the person who is giving the oral.
Lilly: "So like omg, i was
giving head to Billy and right before he came he
took a shit in his hand and slapped it on my back!"
Leah: "LMAO he so gave you a swahilian
backslap!"
