Guys, what's a toxic trait other guys sometimes have

I have a coworker who is walking checklist of toxic traits and red flags. Here are the highlights:

• only helps attractive younger women or men who can do favors for him
• sticks his nose into situations that he has no business with
• tends to work on high visibility projects while ignoring his actual job
• has a BT speaker that requires wheels and extended handle and plays his shitty music loudly
• honestly thinks he's all that and a bag of chips
