a person who is mopey and a downer, needy, and selfish. they soak up all of your attention. they are incapable of giving anything back.
a wet mop might be a man you are dating who constantly needs attention from you, but then never gives you attention back. when he is around, he is inconsistently happy/mopey. when you address to him that he is sending you mixed signals and/or tell him that he is making you feel bad based on his actions, he assumes no responsibility for his actions or inactions.
