San Francisco Switcheroo
This is a sexual term referring to a particular sex act where a man receives a blow job from a woman, cums in her mouth, and then the woman (or could be a man) pretends to swallow, then turns to embrace her partner in a passionate kiss, thereby open-mouth kissing him with his own cum in her mouth. Hence, San Francisco Switcheroo (almost gay, not quite)
Man: You gonna swallow right?
Woman: Of course
Man: You better not pull a San Francisco Switcheroo on me cause I'm not okay with swallowing my own cum.
Woman: Of course
Man: You better not pull a San Francisco Switcheroo on me cause I'm not okay with swallowing my own cum.
San Francisco Switcheroo
When your partner has fallen asleep after sex, quietly slip out and exchange places with a friend who's the same sex as your partner (or the opposite sex if you're homosexual). After they've gotten comfortable together, call your partner or knock on the window. Surprise!
I donkey punched her the other day and she got me back by pulling a San Francisco Switcheroo on me.
