A really half-assed apology.
(Meh Culpa is a portmanteau of contemporary slang and Latin. See Mea Culpa. ...or perhaps admittedly a cheap combo of street and pretentiousness.) Um, Meh Culpa?
(I just made this word up. Is that okay by UD guidelines? ...or is it like "original research" on Wikipedia?) If it's not okay, Meh Culpa. ;-)
You are totally right, I did make a spelling error in my IM message to you last night. Meh Culpa.
