@AmishRakeFight See, I'd roll my eyes a lot more at someone who's trying to show off a PC's IC hacking skills by pasting port scan command in their poses than someone who just name-drops a bunch of TCP/IP jargon randomly ("I'm using the mac address to do a reverse lookup on the DNS!") while hacking the FBI database using an iPad over the Starbucks wifi. Bring it on!
And believe me, I am peeved sometimes by seeing people roleplay things which are actually impossible to do with computers such as hacking into machines which aren't even networked. Even that's preferable than turning the scene into an self-promotion exercise.
A bit of jargon just to provide a taste of authenticity at the same ratio they use on TV (i.e. not so much) is perfectly fine. Going too far either way irks me.
