blame it on _____
If I don't do well for my exam, can I blame it on the bugger behind me who kept kicking my chair? Don't know what was his freaking problem, couldn't keep his bloddy elephant trunk to himself.Maybe I should have alerted the invigilator that this guy was trying to pass me morse code message.

















maybe he's one of those who didn't study and so was trying to irritate you (and anybody else for that matter) so that you'd score badly so that he'd score better... u get what i mean.
