The act of planting a "raspberry" on the nipple of a woman's breast. Often considered rude... or creepy.
1. Place mouth around nipple, pushing lips firmly against skin - you'll need a good seal!
2. Exhale strongly, creating a "farty" sound.
Girl: What the fuck?! Did you just give me a raspboobie?!!!
Guy: Mmm, yup. My bad.
