The cape codclam steamer, aka cccs, is a sex position. You go to cape cod, dig up some clams in the ocean, and then boil the by forcing them up your gf's vagina.
“Bro I gave my girlfriend a clamtown steamer last night” “damn dude what is that” “I shit on her pussy after I ate her out, that’s a nice clam town steamer”
The ultimate act of revenge upon a cheating girlfriend. This is the process in which you buy a bottle of hand sanitizer and simply remove its label and replace it with a label from a bottle of lube. Use the sanitizer as lube and she will receive the burning sting of retribution.
