There is one every so often

[BLS]

I'll tell this one on myself. (I think there was a similar situation in a thread a few weeks ago, but since it happened to me too I'll tell my version.)

First game of the basketball season, after doing a season of volleyball.

Coach: "Timeout!"
Me: "Tweet" Make the "T" sign for the timeout.

Partner looks at me like "what's going on?". Other coach "Did he just get a technical?".

Me: "No, Blue full timeout".

Partner: "What was the T for?"

Me: Red faced and realizing that I'm not longer reffing volleyball where "T" means timeout.
