Swim Upstream

Euphemism for anal sex.

Brooooooh that slut let me swim upstream last night. Water was a little muddy though if you know what I mean.

She told me I could swim upstream tonight. I railed them intestines.

swim up stream

When you shoot your load into a girls nose. Also could be considered as snorting semen.

This chick was crazy last night, she let me swim up stream.
