A gweef is a male penile phenomenon that occurs when an inexperienced girl performs felatio incorrectly. This usually occurs on the first time a girl gives a blowjob and takes the name too literally. With the pee pee in her mouth, the girl promptly seals her lips around the males urethra and blows air into it. This might cause some discomfort and "WTF!!"ing. As the dude tries to get the air out, by unspecific maneuvering, he suffers a penis fart. Also known as a gweef.
