Excessive fluid from the mouth - a combination of 'to slobber' and 'to salivate'.
An increased buildup of saliva in the mouth, often commences when one hasn't swallowed in a long period of
time, or when one lays their eyes on an appetizing
food.
Slobbervating, however, has a much more drastic outcome, with the whole mouth just overflowing in
spit. How disgusting.
