Effect is worsened/amplified when your member becomes erect, causing extreme discomfort to both your penis and pubes. Common effects include the said person awkwardly wincing and pulling on his crotch in public in a desperate effort to untangle his pubes.
Guy: *grunting loudly while pulling on crotch area*
To have one's erect penis deflate and fall limp while attempting to put on a condom before sexual intercourse. This phenomena can sometimes be attibuted to the de-sensitizing feeling of wearing a condom. Sometimes, a sound similar to a deflating balloon can be heard, but this noise is actually from the flow of air into the the condom's vacuum left by the shrinking penis.
Dude that poor guy was about to lose his virginity to Shrudi but when he tried to put on a condom his penis went flaccid and became a vacuum wrapped sausage.
