When someone acts like they're super smart but then does something so stupid it makes your brain hurt. You yell shut the fuck up because you're too mad to think.
Maaaan, you tried to fix the printer by throwing it out the window. Shut the fuck up!
Maaaan, you said the Earth was flat and then fell off a cliff. Shut the fuck up!
Maaaan, you tried to text your mom with your feet. Shut the fuck up!
