The act of cupping an individuals genitals in the palm of one's hand and proceeding to lap at them with your tongue while making a noise akin to that of a "Murloc" (A fictional amphibious creature from Blizzard's™ "World of Warcraft™"). The most accurate sound a human can make sounds a bit like "mlow mlow mlow mlow mlow!!!"
MLOW MLOW MLOW MLOW MLOW!!!
"LOL, dude my girlfriend totally gave me a murlocing last night!"
