[from BE- + SLAVERMiddle English, possibly Low German; come with slobber]
Slaver or dribble over.
Not only does the mere mention of food make Homer Simpson beslaver like a St Bernard, the mere mention of something that could possibly be construed as sounding a little bit like a food can set his salivary glands a-churning (such as D'oh! and Nuts! said in tandem). We shouldn't be quick to judge him, however, as the average adult generates between 2 and 4 pints of saliva per day and it has to go somewhere. This, I should point out, is a very useful fact to know for the next time a globule of spittle reaches escape velocity mid-conversation and lands in someone's eye. Honestly. Try telling them that. It diffuses the embarrassment every time.
