An asshat is typically someone who is a bummer. Always chiming in with their own opinion, nobody likes them.
(Guy 1): I personally think Trump is on a course to make America great
(Guy 2): shut up you Asshat.
An asshat is someone who isn't worthy of the title "asshole", so they put their hole on their hat therefore making them an asshat.
"______ (name), don't be a fricking asshat"
Similar funny quote:
"______ (name), get your head out of your ass it isn't an ass.
A person with their head up their own ass so far that they are wearing a hat.
That ignorant, compassionless woman who posted a horribly thoughtless and insensitive comment is an asshat.
Donald Trump and his cronies
That asshat is going to build that wall.
