Facekeyboard
When you’re talking to someone online who’s a total braindead and won’t stop arguing with you even though you’re clearly right.
My cousin was arguing with me for 30 minutes about why the sky is blue and I facekeyboard'd because he said 'it's because of magic.'
I was trying to explain that 2+2=4 and my friend said 'no, it’s 5 because I say so.' I facekeyboard'd.
I was playing a game and someone kept telling me I was wrong even though I had the highest score. I facekeyboard'd so hard the game crashed.
