When your wife asks you if you heard what she said and you answer. "Lima Charlie"
When a co-worker brags on a peer and you tell him to "stop humping that noobs ankle"
The one time you beat your son at wii archery, you scream, "I PWN U!!!!!"
When you end corporate emails with <S>
When you start family meetings with, "radio check?"
After being dressed down by the boss in a weekly group status meeting, with a raised voice you say, "it'd sure be nice if I got a check 6 from one of you"
You don't get a corporate email answered on time and use "lag" as an excuse to your boss
