Used to describe a person that is displaying homosexual behavior, usually being very descriptive about homosexual intercourse. May only apply to males.
Person 1: I want James Charles to stick his dick in my ass and squirt so I’m farting Elmer's Glue for a week.
Person 2: What the fuck quit being a little Sus Monkey dude gross.
The minute that the sun appears, Sunmonkeys put on their shorts, parade around in sunglasses and try their very best to get a tan. They are usually the first ones to get sunburn.
Similar to a 'sun worshipper'.
"It's so sunny! Quick, hand me the suncream!"
"OMG, you're such a Sunmonkey"
