Someone who is totally and irrationally devoted to Trump and the MAGA movement.
My friend recently had a full frontal lobotomy, suddenly started wearing a MAGA hat and has put up photos of Trump and Putin in his house. Is he now a MAGA-mong?
My cousin Cletus donates his entire welfare check to Save America and has to steal cars to feed his 11 kids. Surely he must be a MAGA-mong?
