Its the slippery gecko, you shove your partner against the shower wall while kissing them, but when you quickly try to put ur penis in their anus you say to them "15 minutes could save you 15% or more on car insurance with geico"
Man 1: "i gave my girlfriend the slippery geico the other day, she wasnt too happy about it because she uses progressive car insurance"
Man 2: "did you tell her exacly HOW much she could be saving with geico?"
Man 1: "of course i did, she climbed up the wall screaming halfway through me saying it"

a slippery doo da is when you fuck a girl hard in the ass then you eat all her hair on her scalpe until she is bald then you let her shit on your eye lids as you blink her shit gets into your eyes. then she makes out with you while you both have her shit in your moufs. It is also known to be done with dogs,cats,mouse any small woodland animal would work nice. and if you really want to get down you can use a elephant. some people like to kick it up a notch and get knives and cut open there partners insides and have sex with there internal intestines
