sounds more like the guy was in a std suit, most likely a new player which cant aim well and you just dodged everything with your caldari suit lolspeed and survived with massive shields. and then you instagibed him with a core grenade he probably didnt even knew that he was invisible

So I get hit, from nowhere? A trail off bullets is just coming towards me from behind, out of thin air!

- Ah, this most be one of the fabled invsible dudes I've been hearing about.

I retreat, naturally, under one of the, well, buildings of some sort.

I keep an keen eye which is kind of silly, which way will he come? Front or rear?

As I move to the rear I get shot in the back, yes off course, he would come in the front being invisible and all.

I try to fire back but only get the occational hitmarker, in mere desperation I start to coock a nade. I hold it for about 2 seconds and my shields are now depleted, which is a bad thing when you are in a cal logi suit....

I toss the nade in the general direction of where the bullets are coming from. It stops in mid air and falls to the ground, Bingo - in your face sucker!

I see a +50 pop up and I look down and see that I have about 20 armor left.

So this guy attacks me twice while being invisible and can't take me out.

I couldn't help it, I sent him a "Scrub" QQ message....

For some strange reason while I was reading this there was softporn music playing in my head

You got the wrong guy I never got any hate mail.
P.S Didn't this happen a several days ago?

I wouldn't know what that sounds like, link?

Not talking about you. And you're right there was some Seraphim dude (you perhaps) in a game a couple of days ago, can't really remember what happened then.
