Ah, the folly of youth.
Being 19 years old is a heady experience, pumped full of hormones and zest for life... many youngsters can make fools out of themselves in the pursuit of hedonism.
Add to that a hefty dollop of entitlement and you end up with the precocious mess that was Patrick Schwarzenegger on Saturday night when he was ejected from a club in Hollywood for spiralling into a foul-mouthed rampage after sneaking in with a fake ID.
Obnoxious: Patrick Schwarzenegger was heard telling friends he was going to beat the f*** out of the DJ" after reportedly being kicked of The Sayers Club in Hollywood on Saturday night
The fruit of Kennedy and Hollywood loins, Patrick's pedigree is about as high falutin' as they come but he still managed to sneak in the Sayers Club in Hollywood with a fake ID on Saturday.
That's a felony, which means a fine could be anything from $1000 to a year in jail but Patty's father Arnold, 65, probably knows that as he was governor of California from 2003 to 2011.
But he wasn't noticed until he started throwing ice cubes and threatened to 'beat the f**k out of the DJ.'
It was all caught on camera by celebrity website, TMZ.
'I'm gonna go beat the f**k out of the DJ,' he told a group of friends while outside the club.
He then added: 'Everyone around me wants to beat the f**k out of the DJ ... [it sounds like Patrick says 'gay boy'] ... I'll beat the f**k out of him.'
'He kicks everybody out of his table, losing money for the club, losing money for the owner.'
Then he attempted to climb in an SUV but was told to go away by the driver and proceeded to obnoxiously wave his hand in the unlucky motorist's face.
However, like most people, Patrick didn't feel too cocky about it all in the cold light of day.
He took to his Twitter to write: 'Excuse me language, I apologize.'
Before adding, 'live and learn, hope everyone has a blessed day.'
