look up any word, like dirty sanchez:
 
1.
nickname of a hockey goalie legend named jacob sloan. the word "sloanwall" is derived from the word "stonewall" which described jacob's ability to stop anything, just like a stone wall
CORY: "man, sloan is stoppin everything in net tonight bro!"

MARQUIS: "i know dude he's like a stone wall!"

CORY: "more like a sloanwall AHAHAHA"
