Facebook ambush
You lurk on Facebook like a ghost until your crush shows up in green, then you pop out with a message, comment, or tag like you're trying to scare them.
You posted about your bad day. I tagged you before you could even finish your rant.
I sent you a message right when you logged on. You had no idea what was coming.
You commented on my post. I replied so fast you couldn't catch your breath.
