When a girl has cum in her hair, she is said to be wearing a Cumbrero (pronounced like sombrero)
::While at a party:::
Hot Bobby Arrives from upstairs after leaving with a random hoochie-
"Yo, I nutted in some girls hair just now, it was soo grimey"
Nick Twitch- "You gave her a cumbrero!!?? Sick dude"
Hot Bobby- "We gotta get out of here guys"
