The best Christmas cookie to ever be consumed, consisting of peanut butter-based dough rolled in sugar with a delectably delicious Hershey's Kiss placed in the center.
"Where's Jake?"
"He's downstairs eating peanut blossoms with Allison."
"Is that an innuendo?"
"No."
"Oh."
Named after the Christmas cookie, it is a sexual act in which one inserts one or more Hershey kisses into another persons asshole and proceeds to lick/eat the chocolate out as it melts.
Hey did you hear about jb? He just bought a bag of Hershey kisses for his boyfriend. He wants to try a peanut butter blossom tonight.
