The act of splitting the urinary meatus (a.k.a. your penis hole), splitting the head into 2.
Elijah: Man, I haven't masturbated in like 4 days. Know of any good internet porn? I'm like... fully loaded.
Random Stranger: Yeah, turn off safe search on Google Images and type in "Headsplitting"
Elijah: Cool, what is it?
Random Stranger: Two girls sucking on one guys head. Get some lube and prepare yourself for about 15-30 minutes before looking it up. You don't want to cum to early!
