(N.) An Urban Dictionary user who always posts definitions to a word on here a day or two immeadially after someone else has just put them in. They always add on to brand new words that a more popular author just puts in, and in a sense, "Follows You Around" like a Shadow.
If you check an UrbanShadow's Word Bank, it'll have the exact same words (and probably order) as someone else, who doesn't need to "Leech" off of other's definitions.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
"Base we've got some square groupers floating outside of Miami harbor."
