The fine lady with the blackberry was giving me terrible head last night. GOD bless her. But then she proceeded to scroter-boat me. It was a fucking game changer.

Whilst manipulating the scrotum with your mouth, shake your head back and forth making a "motorboat" engine sound.
It's the male version of the motorboat.
Last night, Janine was circumnaviagting my scrote and then she went crazy and scroterboated me. I may now marry her.
