Pseudo Example:
This is another non-example. Just Herbie swinging his head around, saying Someone? Turns out to be an insulting turkey looking for a fight. Herbie and perky Turkey get into an all out brawl wrestling on the ground.
Pseudo Example:
Now here is Dad, not an adversary, not HAW-HAW-ing and not really with two heads. Since Dad and Herbie are Popneckers, maybe he's "popnecking".
