rusty tinny

The rusty tinny, when your homeboy with a big thick erect dong comes up behind you while motorboating a large breasted woman, so you proceed to bat his cock while making engine noises and going nip 2 nip with your lips on that hoe. Akin to driving a tinny with an outboard motor.

Yo my homie walked in on me and Brittany motorboating, so I gave him a rusty tinny and helped a brother out.
