A sex position. When the male grabs his testicles,and puts one on the side of the penis. Making it to appear like an airplane. Having the women spread-eagle, then running full force towards her hopefully making it in.
john: hey jess... jess: yea? John: dude i did the kamikaze on my girl. I didn't make it in, I fucking sprain my cock. jess: o shit where are you at? John: Hospital.
