Nigel Farage, who led the British campaign to leave the European Union, also made light of sexual assault claims against Trump.
In an interview on national British radio station talkRADIO
, Farage said "couldn't be happier" with Trump's election to the White House.
"The revolution of 2016 just keeps on rolling!" he said jubilantly.
Farage is the former leader of anti-European Union, right-wing UK Independence Party (UKIP) and campaigned with Trump
during the 2016 Presidential race.
During the interview, Farage said Donald Trump's victory was a "big opportunity" for British business and the President-elect would push for a trade deal with the country.
"That Obama creature, loathsome individual who couldn't stand our country, said we'd be at the back of the queue, didn't he?" Farage said.
"But what was interesting was that Trump said we'd be at the front of the queue. Listeners, bear this in mind -- however imperfect Donald Trump might be, and goodness me he is ... he loves our country, what we stand for and our culture."
Speaking to CNN's Richard Quest after the US election, Farage said 2016 had been a huge victory for his and Trumps' ideologies.
"What it's all about is -- do you believe in nation-state democracy, or are you happy with bigger supra-national forms of government where decisions get taken elsewhere?" he told Quest.
'Don't touch her for goodness sake'
Farage also referred to sexual assault allegations against Trump, made by almost a dozen women
"I'm going to say 'Come and schmooze, Theresa. Don't touch her for goodness sake,'" Farage said, as the hosts laughed.
"If it comes to it, I could be there as the responsible adult couldn't I? Make sure everything okay."
Farage's comments about Obama and May were widely covered in the British media and were slammed by former Blair Government Communications Director Alastair Campbell.
"He does talk about Barack Obama in a way that is really quite unpleasant ... I don't know whether there's racist undertones or not but I do think that Nigel Farage says things largely to get talked about," he said on TalkRadio
'Snobby about me'
Meanwhile, Farage says he would "think very hard" about acting as a mediator between the British government and President-elect Trump, though he claims such a role remains unlikely.
"The British Conservative Party are incredibly snobby about me, they find it very difficult to even have a conversation with me," he added.
Farage has been effusive in his praise of Trump in recent months and believes the two have much in common.
"I believe in nation-state democracy, I believe in controlling borders, I believe we've got to confront the threat of Islamic terrorism, and President-elect Trump believes in very much the same thing," he said.
