The experience of feeling sure that one's hook up reminds them of a previous hook up.
Dude 1: "Damn I have this sinking feeling that I've motorboated those before"

Is the experience of feeling sure that one has already witnessed or experienced a current boob, even though the exact circumstances of the previous encounter are uncertain and were perhaps imagined
