appalled viewers after he failed to turn up to Hollywood's biggest night and wound up taking home his third Academy Award.
despite being nominated for Best Supporting Actor - a move which both offended and impressed netizens.
Penn became the fourth male actor to win three Oscars on Sunday night after he beat out Benicio Del Toro, , Delroy Lindo, and Stellan Skarsgard for the trophy.
But his absence infuriated X users who suggested future shows cease awarding trophies to winners not present at the show.
'There should be a rule that whoever doesn't show up because they don't give a s**t about the award doesn't get it either, like in a raffle. Didn't come? Next on the list, please. Exception would be for health reasons. Sean Penn doesn't give a damn about this award,' one reasoned.
Another was stunned by the fact that Penn had something 'better to do' than attend the Academy Awards: 'I can't stop thinking: What the F**K did Sean Penn have better to do than go to the Oscars???' one inquired.

Penn won the trophy for Best Supporting Actor for his role in One Battle After Another
'Unless you have a good reason not to be in attendance, if you can't be bothered to show up to the Oscars, your award should go to the runner-up. Sean Penn. This is about Sean Penn,' another wrote.
'It pisses me off when someone wins an #Oscars and doesn't even show up. Sean Penn couldn't care less about that award,' another posted.
One impressed X user called his snub a 'flex'
Another didn't see what the big deal was about Penn's absence
'Sean Penn couldn't be here this evening or didn't want to, so I'll be accepting the award on his behalf,' Culkin joked.
