When you cum/come out of nowhere.
A surging sanders is a guy who always Cums early.
As first seen on Fox news when a newsman said that Hillary was "worried about a surging Sanders" in the Presidential Election of 2016.
Comedy show genius The Daily Show with Trevor Noah defines the word jokingly as an urban dictionary word. Little did Trevor know that his word would become embedded within the Dictionary.
"She is worried about a surging sanders"
"Ah, Yes. A surging sanders."
"We all know he is a surging sanders"
When somebody over the age of 60 pops a random boner for the first time in a long time.
My grandpa got a Surging Sanders while watching Price is Right. Gross!
When you come (cum) out of nowhere; when you orgasm and/or ejaculate unexpectedly.
The term was first coined(or at least made famous by) the new host for The Daily Show, Trevor Noah, in allusion to Bernie Sanders who as of Feb-2016 is tight in the race for the Democrat nomination for president. He was an independent Senator from Vermont who decided to run for president and has had nearly zero media coverage during most of his campaign. Even with that factor in play he seems to be "neck to neck" with the "establishment" candidate, Hillary Clinton in many polls (surpassing her in some). Somewhat expectedly he has had much more media cover during the las few months. Thus, he came out of nowhere and no one saw him coming. The Surging Sanders.
(noun) I had a Surging Sanders the other night, couldn't help it, both my partner and I where quite surprised.
(noun) That guy is a Surging Sanders; I mean it, I didn't see it coming, suddenly it was all over me, nothing special was happening... I don't even know.
