Someone attempting to hide their dumbassness by repeatedly lauding their one and only (generally small) victory to their friends or a random crowd of strangers, depending on who is handy.
Ted: I slept with Rebecca Stillworth and it was freaking amazing! We did it like eight times and I think I made her cum twice that cuz I'm so talented. Seriously, she even told me that they should make a statue of my penis.
James: I wish Ted would stop boasting about that.
Kevin: I know right? It happened like ten years ago.
Steve: You'd think he'd have something else to talk about by now.
*They all nod in agreement, except Ted who continues with his boasting, oblivious to his friends' disgruntlement*
