Rokk: Lightning lad! You might want to
take your AC foot out of your DC mouth Stop talking BS?
before you short yourself out. His batteries ran out?
Lightning lad: Grife,(what's that? I may have misheard this one.) Rokk.
AC-DC refers to speaking without thinking, or being ambiguous or even not consistent with beliefs.

Short out is an electrical term which has something to do with the current being on overload and causing the circuit to go out, sometimes with sparks, etc.

Might grife be, actually, cripes, a mild expletive?
Thanks, Philip! And cripes makes sense.Emotion: smile
