A Trumpster is an avid supporter and follower of Donald Trump. He is their light in the darkness. They do not functIon like your average run of the mill Republican, as they only quote Fox News in their daily debacles with every other political party when it is convenient and in favor of the almighty Trump.
Child 1: Did you hear Jimbob tell Juan "You don't belong here, and you should be punished for your parents' decision to come to America for a better life, Heil Trump."
Child 2: Yeah! He identifies as a Trumpster. Unique viewpoints they have
A supporter of Trump acting out, because they didn't get their way, or feel the need to rant about something others have done that conflicts with their political worldview. Often accompanied by the burning of products (see Nike), and the words libtard, snowflake, emails, and mentions of Barack Obama.
Jim Bob is a Trumpster. The dumb ass actually blames all of America's problems on immigration and Obama instead of the Republican party and its inability to pass a job's bill.
An exceptionally stupid person that is fond of/voted for the Raging Cheeto. Also a word for a fucking dumbass. Derived from the words "trump" and "dumpster" since the two are so alike.
