Tight shorts in general on males. So tight that testicles are
bulging in the crotch. It gives the appearance as if the wearer is
smuggling plums in his shorts. Hence the name "
Plum smugglers". These shorts are often worn by American tourists abroad.
"Damn, how can you fit your balls in those
plum smugglers?"
American tourists usually wear
the plum smugglers with a pair of birkenstocks (sometimes worn with socks).
Lt. Dangle from the show
Reno 911 integrated the plum smugglers into his uniform.
