facebook single
A facebook single is someone who's in a relationship but still says they're single so they can flirt with others. They're like a kid who still eats the last piece of cake but says they didn't take it.
He said, 'I'm still single!' even though he was seen kissing her at the park.
She texted me, 'Still single!' while her boyfriend was messaging her all day.
He said, 'I'm single!' even though he was seen holding hands with her at the store.
