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 are you serious? I can't believe you, out of all
people, got me to max out."
"What?!?! I got an F on my Spanish exam? My
parents are going to max out!!"
