Having an entitled/victim mentality. Having more then others and whining and crying about anything that doesn't go your way. It's never your fault and someone else is always to blame.
"Dude I failed the test. This teacher is out to get me!"
"Man stop trumping, teach doesn't have it out for you... You just didn't study."
Whining about something that is unfair, really unfair, the most unfair of all unfairs, when it’s actually the truth.
Dude 1: “I just got fucked over. It’s unfair.”
Dude2: “You had an affair with a porn star, you lie at every opportunity, you’re a complete crook in business, you’re a megalomaniac and a sociopath. Quit your Trumping.”
Dude 1: “Whar’s Trumping?”
Dude 2: “”The new definition for whining, check out Websters.”
