A person who often becomes excited and aggressive over trivial things. Specific stimuli especially invokes excitement from one who is a live wire.
Watch what you say, because he's a live wire, he gets so mad over the tiniest things, especially if you tease him about his extensive shoe collection. But if you talk about something he likes, he'll become really excited and happy!

Somebody who lies on the internet.

Somebody who has broken English as mother tongue(tounge in Livewire lingo).

Somebody so cool he has a pregnant under-age internet girlfriend, 3½ PhD's(and counting). He can also travel to Greece(to meet his e-gf) in record time(and probably does not have to leave the room)..
Oh did I say that they used to be brother and sister before they eventually fell in love?

WiSeMAn: live wire, what do you do for a living?
Livewire: I go to school WiSeMAn.
