verb: it's when you shit in your hand and throw it at somebody. it's derived from the word kamikaze which was a Japanese fighter pilot during World War II who would crash his plane into enemy targets, but modified to include the word crap in it as a prefix. The crap flying through the air is like the Japanese kamikaze airplane flying through the air and hitting the target thus the resemblance of kamikaze to crapperkaze.
Terry: Frank was being a true cockstar last night and I did a crapperkazee to him.
Franklin: Yeah, I heard that some of that got into his mouth.
Sylvia: Yeah, he puked up blood after that shit went into his mouth.
