e-fenestration
When you get caught doing something dumb and you accidentally switch to another dumb thing like you're trying to hide but it's just making it worse.
I was watching a YouTube video of a cat falling off a building, and my mom walked in, so I alt-tabbed to my math test and got caught with my pants down.
I was messaging my crush and my dad walked in, so I alt-tabbed to my email and got caught doing both.
I was playing Fortnite when my boss walked in, so I alt-tabbed to my history homework and got caught with my crush.
