padraigh
Padraighs are usually amazing people, but they're also really loud and think they're the smartest person in the room. They talk way too much and never shut up.
My cousin Padraigh tried to explain quantum physics at a BBQ. No one asked for it.
Padraigh said he invented the wheel. Then he said he invented the internet. Twice.
At the party, Padraigh talked for 45 minutes about his cat. His cat didn't even blink.
