I play Heavy alot. I also talk a fair amount over chat and will tell a medic healing me to get health if they didn't pick up one when they were half dead, or even retreat so my medic cna get health.
So this morning I'm reading the TF2 Wiki cause I'm bored and my wife comes in and starts talking..
Wife: What are you reading?
Me: Nothing
Wife: Medic? I recognize that word
Me: Oh do you?
Wife: Yeah, you say it every night
Me: No I don't...
Wife: yeah you do...
Me: Oh.. Right. I tell the medics to get health and stuff...
Wife: that and...
SPY! SPY! SPY!
I died laughing... I guess you never realize how dumb you can sound to someone who isn't playing

(EDIT: You may or may not have had to have been there for the funny
