Bosnian Mountain Time

Definition:

Bosnian Mountain Time is the time when you leave the party and/or bar, after intending to "have just one drink and leave".

Exemplification of usage:

Me: Just so you know, I'm planning on leaving at nine. Jen: OK, me too. Me: Oh, shit, it's after nine! Jen: Let's leave at nine o'clock Central Time.

(time goes by, drinks flow)

Me and Jen: We are leaving at nine o'clock Pacific Time (shots glasses clinking).

(time goes by, drinks flow; bar is closing)

Jen: What time zone are we leaving at? Me: Fuck, we're on Bosnian Mountain Time now! (said so - slurry sub-titles are needed)
