1. When a person, after giving someone head, holds the cum in their own mouth and then makes-out with another individual (usually the one that received the blow job) and transfers the semen into that person's mouth.
2. When someone gives a blowjob with some very cold substance, usually ice, in their mouth.
1. It wasn't long after she finished his blow job that she started snowblowing so he could get a taste too.
2. I didn't know why they took ice cubes into my bedroom, but then I walked in on the two of them snowblowing- it must have been pretty cold.
