When someone gets so mad that it has the
potential to ruin their whole day. Noticeable when someone lets their anger leak out,
usually described in forms of
yelling or raising their voice in defense.
When I told josh I screwed his
girlfriend he maxed out.
"Dude

"What?!?! I got an F on my
Spanish exam? My parents are going to max out!!"
