A hockey player who was never good but always thought he was good. A flash typically plays deep into their 30s and 40s despite the lack of skill. Flash's are usually relatively nice guys, but they aren't very smart. They also gravitate to the younger rookies on the team and attempt to teach them of all their hockey knowledge, although the rookies seldom listen, which is probably for the best.

There is also often a power struggle between better players and a flash because A flash thinks they're so good that they should be getting all the ice time over the actual skilled players.

When a girl is drunk, a guy comes over and bangs her in all three holes very rapidly. Then when it's all over the girl doesn't know what happened.
Dude Richard there's the girl you flashed last weekend. I still don't think she knows what happened.
