A person that has exceeded the measurable levels of fucktardal asshatery. Their level of stupidity of clearly noticable when they enter the room ... Kind of like blowing a horn announcing their assness.
Wow, my neighbor is a fucking asshorn! But, I would like to donkey punch his daughter.

When a person has exceeded the measurable levels of fucktardal asshatery. Their level of stupidity is clearly noticeable when they enter any room ... Kind of like blowing a horn announcing their assness. An asshorn is usually the fuck face of the office.
Oh shit! That asshorn Jason is here. Don't make eye contact or that shitbrick will come over here. That fucker eats his lunch while taking a shit.
