A funnier, less
old-fashioned way of calling someone a "wet
blanket". Used when referring to anyone who brings down the fun factor of a given situation. Said individual is as much of an annoyance as an relentlessly itchy
scrotum.
"Guys, could you use your 30 cm voices?
People are trying to
sleep"
"Dude, why do you always have to be such an itchy
sac about things? Have some fun already."
