Did you mean Sick or Sick?

Conversation yesterday:

Me:  "How was the meeting?"

Husband and Son:  "Great."

Husband:  "There was a kid with a mullet there."

Me:  "That is sick!"

Son:  "Mom!  (disgusted face)  You can't use that word!"

Sick: Adjective

sick (comparative sicker, superlative sickest)

1. In poor health

   She was sick all day with the flu

2. (colloquial) Mentally unstable, disturbed.
3. (colloquial) In bad taste.

   That's a sick joke.

4. Having an urge to vomit.
5. (slang) Very good, excellent, awesome.

   This tune is sick.

   Dude this car has a fully sick subwoofer!

6. In poor condition

   (sick building syndrome; my car is looking pretty sick; my job prospects are pretty sick)

Just for the record,

when I use the word "sick" and mullet in the same sentence

I'm referring to definitions #2, #3 and #4

with an emphasis on #4

 my son, on the other hand, is going with definition #5

and is now determined he'll be sporting one himself.

Could I get you some Polo to go with that?
