Covfefe
Covfefe is when you're trying to make a bad decision on social media or trying to text an ex while drunk on a Tuesday night and someone with more sense than you tries and succeeds to yank the phone out of your hand, but not before you write 'covfefe'. Also popularized by Trump in a frantic midnight tweet on May 30th, 2017 in which he was once again complaining about bad press coverage, or 'covfefe'.
Girl: Man I almost texted my ex-boyfriend last night drunk off my ass eating a McChicken and a 10 piece McNugget meal until my friend successfully covefefe'd the phone out of my hand. Clearly dodged a bullet there!

Guy: I was totally going to blast my boss on twitter but my friend talked my off the ledge - another successful covfefe.
