o'glark
A fancy-ass way to say o'clock, like you're trying to sound smart but you're just being annoying
'I'll be there at 3 o'glark, or I'll make you do push-ups.'
'She showed up at 8 o'glark, but it was actually 8:01, and she was still eating cereal.'
'He said 12 o'glark, but it was 11:58, and he was already drunk.'
