British slang

Originating from Jools Holland's 2003 New Year's Hootenanny show, when just as faithful, ol' Big Ben strikes the jubilant 12, Jools runs gleefully into the crowd, straight past the attempted embrace of Rivron. This leaves Rivron clutching only air. As the rest of the audience dance and sing auld lang syne, Rivron is left sporting a look of desparation as his only true friend leaves him high and dry at the start of another year presenting Holiday programmes from Skegness.

Therefore, to be Rivroned is to blanked or passed over in the harshest way possible. The lowest fate that can become an already desparate and desparing man/person.
"i saw my Gran by Spar on Sunday night, but as went over to say high, she saw me and immediately crossed over the road and ran into the Bingo hall."

"That's poor bro, guess you got well Rivroned!"
