guyser

A sexual position in which a man titty fucks another man that has large enough man-boobs to allow such a vile act.

That guy is so overweight that his tits are so huge that you can give him a guyser.

Guyser

The explosive regurgitation of semen acquired during a long bout of oral sex with multiple partners.

I was number twelve in line, so I knew I had to get off quick before she gave me the guyser.
