Not having a go at everyone who uses 'OCD' in this fashion but what you mean to say is 'what are your obsessive habits in destiny?' OCD actually stands for Obsessive Compulsive Disorder and is a serious diagnosable mental illness which really should'nt be trivialised in the form of a pop culture reference. It seems to be a common thing and I've never seen it used in a malicious way. Its pop culture usage does take away from its importance and its medical intent though and the only way people become aware is if you tell them. :-)
