mister party 

The ass clown who shows up uninvited to a party, gets shitfaced, says inappropriate shit, gropes female partygoers, and makes everyone uncomfortable.

Stays long after everyone leaves & doesn't even offer to help clean up!

If that good-for-nothing, creepy bastard shoes up... stab 'im!

Party trick master 

Someone who's got party trick after party trick after party trick, but leaves you no reason to ever miss their presence after the party. Similar to a puppet master.

The party trick master has mastered every one of her party tricks, but when the people she thought of as her puppets are no longer around, the difference between her and them is they don't miss her presence or mind being alone, away from from the party, away from the group.
