look up any word, like donkey punch:
When you hear the expression that somebody has 'buttery teeth', it most likely will mean that they have obserdly yellow teeth. You might even hear the term, cheddar teeth. Which is basically the same thing.
'Damn, look at that bitch's "buttery teeth" OR
'Holy shit, shes gotta enough cheese on them teeth to feed a homeless shelter!'
