Pulling a Leo is when you are talking to someone on an insant messenger and they give you their life story.
Person 1: Hey

Person 2: Hey, sup?

Person 1: Oh nothing, I just was like at this grocery store and I got like heaps of stuff and then I came home and played some video games, guitar hero 3 and final fantasy 12 to be specific.

And like long story short I'm on the computer right now and I'm sitting down on a chair, breathing, blinking, moving slightly every few seconds and typing.

Person 2: Pulling a Leo eh?
