To be somewhat amusingly
crazy but not necessarily in a bad or threatening way. Someone can be temporarily kooked due to an event or generally be kooked all the time. For instance, Molly
Shannon and Andy Dick are kooked but Tom
Cruise and Hannibal Lector are not.
This is a variation on 'kookoo for cocoa puffs'.
1. "I just saw Brad Pitt on the street and I started screaming like a banchee and whipped my top off to get his attention. I totally went kooked."
2. "He makes his cat wear an Elvis costume and does air
guitar to
Carly Simon meaning he's friggin' kooked."
