It comes from the name of the ex Formula One driver Mark Webber. He was "flying" with the car many times.
He did wheelies, and sometimes he really took off with the car after a crash... and before an other crash, like in Valencia, in 2010.
In his pre-F1 years, he was driving at the Le Mans 24H and guess what? He was flying with the car. That was a horrifying crash, but he survived without damage, he simply walked away.
So when someone "flies" with his car, he is simply webbering.
Räikkönen and Maldonado were webbering in the second free practice of Bahrain GP in 2014.
When a pissed out nigga comes home from a party saturday night and picks a fight with his facebook friends he has never met.
It helps if he also accuses said friend of being a racist for calling him a nigga.
webelling in a more general sense , can be the tendency for grown adults to channel their hormone imbalanced grandma on the morning of thanksgiving, when writing stuff on the web.
Brian raney was bwebelling against his world full of teachers (mom dad,wife, school) when he lashed out at a youtube clip I posted on facebook.
Sarah Palin can be found webelling against her teenaged kids , on her facebook page, in Alaska.
