This is the part of a male's or female's anatomy that accepts the jizzum. Not to be mistaken for the same part that straight people have, a Chadhole usually hangs a bit lower and, over time, develop flaps that vibrate loudly when gas in pushed between them. The flaps become larger and hang lower the older they get. Eventually the flaps have to be surgically altered in order to contain them in the person's extremely short cut off jeans.
This unusual characteristic is very prevalent in Lebanese communities where often each tribe gets their own "Chadysexual" and they over use his Chadhole.
"Hey Ahmed, look at that shemale, is it a guy or a girl? I can't tell because it looks like it has flaps but it is very hairy on it's face too"
"Bro, those are just the flaps to his Chadhole. He is a Chadysexual from way back"
