Slang for a young girl's vagina. The term is derived from the children's drinking cup. May also be related to the sippy noise of the sippy cup in reference to cunnilingus.

after ejaculating into your partners mouth, they spit back out the seman on to your erect penis....and then suck up or sip it back up into their mouth...giving the illlusion of drinking through the straw of a childs sippy cup!
Dude that after that Dawn girl gave me the best hummer of my life, she spit out my jizz back onto my cock and slurped it back up like juice out of a sippy cup!

This is a secret code name for getting head usually said by the male, who received said action. Suction. Cylindrical Shapes. It's all there for the imagination to see.

With emphasis on the "PP", this is when you jam a straw in your cock hole moments before you are about to spray a hot load so that your partner gets to have a relaxing drink as opposed to having to comb cum out of his/her eyelashes or nostril hairs.
Barbara: My bf is such a gentleman. He offers me a siPPy cup at the end of sex.
Friend: My bf is a prick. He covers me as if I was under the huge overturned 200 gallon bucket at the water park!

When a female's vagina is flowing wet from excitement (she is horny or wet) and you give her head. It is like drinking the liquids from a sippy-cup.
She was my sippy-cup, she wanted me.
