Portalingus 

Performing cunnilingus while having a bowel movement in a portapotty.

I told the lady in the portapotty id give her a good round of portalingus after busting in on her to take a shit.

Portlingus 

Very poor cunnilingus caused by your boyfriend being too drunk from visiting breweries in Portland Oregon.

Girl one "Damn Steve's tongue was all over the place last night. He thought my clit was a punching bag. I knew I shouldn't have taken him to Rogue and Deschutes."

Girl two "That's Portlingus for you."
