A childish game played in the eighties where one would run into someone intentionally on a playground and say to them iceman in an excited fashion and then walk away.
After bumping into an acquaintance and nearly knocking them down I played it off by saying iceman and went on my way.
An Iceman Goal is an extremely lucky or a cheap/glitch goal scored in EA Sportsvideo games. The majority of Iceman Goals are scored in NHL or FIFA. These goals will make your opponent mad, but you can do nothing because of it.
Him- "Dude how did you win?"
You- "I scored an Iceman Goal in OT"
Him- "You bastard"
You- "I know"
