facebook single
A facebook single is someone who's got a girlfriend or boyfriend but won't admit it. They're like a sneaky kid who eats the last cookie but says they didn't touch it.
'I'm still single!' he said, while his girlfriend was sitting right next to him at the movie.
'She's my best friend,' he texted me, even though they were holding hands at the party.
He posted 'Looking for love' on Facebook, while his ex was messaging him every hour.
