Why do guys poke me on facebook?

[Megan]

So junior that I've talked to a couple of times in my sales and marketing class poked me on facebook.
And I don't know we've barely ever talked so I was kinda wondering WHY he would poke me on facebook? He didn't strike me as one of those over-the-top-flirt-with-anyone-who-has-a-pulse types so I don't really think thats it
I'm probably reading too much into the situation but I've always been curious why people (more specifically, guys) you don't really know just poke you on facebook. It's not like they drunk-poke you or anything, I'm pretty sure most of them are conscious of the fact that they are poking you even though they don't know you..

Yep if you guys could give me you're opinion that would be mucho appreciated
Oh also he's already my friend on facebook...
He's not creepy or anything as far as I can tell.

I poked him back but just out of curiousity.. I usually never poke back people, I never really saw the point. And now we're kinda caught in a poking war and I have no idea what the point is.. I'm just pretty clueless.

to become a friend of yours

because they cant poke you in real life.

he's hoping you are sitting around on facebook, and wants to talk to you (probably wants to "date" you) - and doesnt want anyone else to know that he is interested

Nah he just thinks your worth putting himself out for.

bc poking on fb is fun

to get into your pants via the internet .... but really its probably just harmless flirtation. DONT over think it because men rarely over think that kind of thing

Personally I just think it's a useless feature on FB.

Probably meant for people who have nothing intelligent
to say which is most of the time anyway!

Bit like the one I read the other day which went "I have
just done a big smelly fart that smells like cabbages!"

Who really cares that much on someone's bodily functions?

What's the phrase? Too much information?
