Coined by singer/producer/writer The Dream in the song of the same name in 2007, to falsetto is to reach an orgasm during sex or a sexual act, and scream in a high-pitched tone. Usually executed by females, but can also be done by males.
Hey dude, you should've heard me and my girl Tasia last night. I made her falsetto so loud i thought my ears were gonna EXPLODE!
Back in the Renaissance period (approx. 1475-1600)the Roman Catholic church did not approve of women singing in the choir. Because of this, they castrated young boys in order to keep their feminine quality so their voices wouldnt change and they could sing as high as a woman. This went on until 1903.
Tariq: "Yo man, did you lose your balls?"
Ferdinand: "Actually, yes. I am a falsetto in my church's choir."
