Keep that same energy or KTSE essentially means that you would like for another
individual to continue to
act (in terms of attitude, in relation to actions) the
way they were acting during a previous encounter.
Jimmy *talking to Steve*: Bro, if I fuckin' see
Tommy near my girl again, he's getting his ass beat.
*Steve is a snitch ass bitch and tells
Tommy of this encounter he had with Jimmy*
Tommy *talking to Jimmy*: Jimmy, keep that same energy you had when you were talking to Steve. I'll see you when class gets out.
If Jimmy were to engage in a physical altercation with Tommy, he would have kept the same energy. If Jimmy bitched out (the more likely of the
two options, his name is Jimmy), he would not have kept the same energy.
