Bobert, when you say "wack," it's confusing. From the context, you seem to mean "to kill, to put out contract on, to terminate with extreme prejudice." However, that should be spelled "Whack." "Wack" means crazy, outside the norm, undesireable, which I'm sure you would be happy to apply to our Commander-in-Chief in other contexts. There's also "Smack," which might fit in your particular reference, meaning to hit, plow into, deliver a blow.

So for quick reference, please cut and paste the following:

Whack - to kill (Gangster jargon)

Wack - crazy (Youth jargon)

Smack - strike (Old jargon)

Please get your acks together.
