Stormzy promised to always remember his grime roots as he swept away the competition at the Mobo Awards with three wins.
The south London musician was named best male and scooped the best album prize for his debut release Gang Signs & Prayer.
Stormzy, real name Michael Omari, also won the best grime star prize and told the audience at the Leeds Arena he would always be "flying the flag" for grime.
Struggling to hold his three awards as he posed for photographs, he said: "This ain't good when you're drunk is it?
"Don't drop them, don't drop them..." he told himself.
On the wins, he said: "Amazing, incredible .... You watch theMobos growing up so this is an honour.
"I'm so proud .. this is dreams come true."
He said the best album win meant the most, explaining: "Best album ... that's the one I'm proud of the most because I put my life into my album."
It comes off the back of quite a year for the 24-year-old, who has performed at the Brits alongside Ed Sheeran and received a Mercury Prize nomination for his acclaimed first album.
The rapper did not have it all his own way however.
He was beaten in the best song category by fellow Londoner J Hus, who won with Did You See while hit track Big For Your Boots missed out in the best video category, with Mist's Hot Property bagging the gong.
The show - co-hosted by Stormzy's girlfriend, TV presenter Maya Jama - attracted a star-studded crowd and saw performances from rap duo Krept & Konan, Britain's Got Talent winner Tokio Myers and US hip-hop star Cardi B.
Birmingham-born Hurtin' Me rapper Stefflon Don picked up the best female award on an evening when Hollywood star Idris Elba was honoured with a paving the way prize for his "achievements in the arts and contribution to British culture".
A paving stone will be embedded at a location in London, where the Mandela: Long Walk To Freedom star grew up.
Accepting the award, Elba paid tribute to the musicians at the event, telling them they were "killing the game".
He added: "I'm so thankful to share this stage and be here as someone who is paving the way for you guys, I appreciate this."
On the success of the Mobos - which celebrates music of black origin and has been running since 1996 - Elba said: "I remember when we used to watch all the big award shows in America and go 'wow I hope we get an award show like that'. Well now we've got one, and it's ours and we own it. You lot should be proud."
