The internet destroys Trump for continually tweeting his ‘desperate' insecurities about Obama

Donald Trump again lashed out at President Barack Obama in a wounded tweet -- and he was buried in online mockery.

The president-elect -- who will keep using Twitter as "a really exciting part of the job," according to his press secretary -- pulled out his phone Wednesday morning to continue the feud that erupted when Obama suggested he could have beaten Trump.

Twitter users quickly heaped scorn on Trump's apparent insecurity -- and his use of the dated "not" quip popularized by the 1992 movie, "Wayne's World."
