Just before ejaculating during sex, the man pulls out a dollar bill (any value), pulls out, and cums all over it, as much as possible --cover that shit-- and then starts to wipe it on their partner's face and other areas if necessary.
Dude, I wet dollar'd Jeff's boyfriend last night.

I got it in! But, she told me to wet dollar her first.
