A term used to secure one's seat on the couch or a chair. When someone must get out of their seat they must call "iggies" in order to protect it from someone taking it before they return. Similar to the 5 minute rule.
"Iggies!" Joe says to secure his seat so his friends don't take it when he has to go to the bathroom.
