Nickname for a man, generally in his early 40's, who is still single and trying too hard to be cool. He is typically a huge Journey fan. He generally stays out way too late, comes home at odd hours and turns on loud music and tries his best to let you know he's a badass who can still party his balls off!
Yo man, I tried to get some rest last night, but Party Balls got home at like 3am and started jamming out to Steve Perry!
