soppy

Soppy describes something thoroughly soaked or saturated with liquid, like a soppy sponge or soppy ground after heavy rain.

In British English, soppy more commonly characterizes excessive sentimentality or mawkishness: a soppy love song, Don't be so soppy.

Someone called soppy is being foolishly emotional or overly affectionate in a way the speaker finds embarrassing or tiresome.

The word carries a mildly dismissive tone, suggesting the emotion is unwarranted or overdone.
