Input: Text: so tifu by calling my girlfriend of just over a year "mom". we were sitting in bed discussing what my account name should be for the account that brought me out of 3 years of lurkerdom. i had one in my mind on my way over and i was trying to remember it while she was talking, but every word distracted me more so i had to interrupt her and all that came out was "but mom". she burst out laughing and i tried to play it off, but she assures me i will never live it down.
