I play this game with certain people I really like, called "That was my nickname in high school."

It is usually inspired by odd noun-phrase snippets, hilarious adjective-verb combinations and come-by-chance signage. The point of the game is to interrupt a conversation with a completely random interjection involving the last words noticed or spoken. Eg. " 'Razor toes' ? Funny you mention it; that was my nickname in high school!" This de-kilters the conversation just enough to be amusing.

"That was my nickname" is based on 'spontaneous decontextualization' (a term I just now invented) and keeping an open mind to the absurd at all times. It's a fun game.
