When someone give the expression of being macho and grandiose. But when the time comes to deliver, they under fulfil and you are left severely disappointed.
Friend A: Did you see Dave last night at the party? He was on fire!
Friend B: ohh I was with him last week, hes nice to talk to but once you get to know him you will see he's just small dick confidence.

When someone, through some means (usually weight loss), gains a large and sudden boost to their confidence that turns them into egotistical dickheads. It can also exacerbate egos for people who were faking it and now that they have real confidence it makes them appear like they're bragging all the time.
Fella: Hey, did you see that Gary lost a ton of weight recently?
Mate: Yeah! Notice how he hates fat people now? And he scoffs at chicks that he previously would have crawled dick first through a valley of glass just for them to notice him?
Fella: I have!
Mate: Ya boy's got a bad case of Sudden Onset Confidence Syndrome.
