Cameljoe (or camel-joe, or camel joe) occurs when a man's trousers/jeans/shorts are fitted too snugly for respectable company, resulting in a splitting of the testicles that is readily apparent through the fabric. This is similar to cameltoe for women, with the exception of two junk-balls being seen.

Person #2: Yeah, that's some serious cameljoe going on there!
