Facebook Boyfriend
A guy on your Facebook friends list who you say is your boyfriend. It's just a joke. He's not real. He's just a guy you added to make your life look better.
I added my pizza delivery guy as my boyfriend. He brings food and a lot of cheese.
My friend made her dog walker her boyfriend. He walks dogs and talks nonsense.
I put my principal as my boyfriend. He gives out detentions and looks cool.
