People keep poking me on facebook?

[SlenderMan]

I have 166 messages of 166 different people that have clicked the "poke" button. What does it mean and why that many?

Just Poke back.

It's just suppose to be something fun. It doesn't really mean anything.

A face book poke is a gesture that is meant to attract another user's attention; you can use it to say hello to your friends. However, a poke is regarded as a feature that has no any specific purpose, each and every user has his or her own interpretation of a poke.
