Word Sponge 

Someone who, when participating in a conversation, chooses to say little no words, generally because they have nothing interesting to contribute.

That guy was a real word sponge, he didn't say a single thing.

mexican sponge 

The blanket used while hooking up in the backseat of a car to soak of the juices. Inevitably it's the Mexican throw blanket found for sale on the side of the road.

It was a good thing I had my Mexican sponge in the backseat because my girlfriend totally squirted all over the place and I didn't want that be soaked up in the upholstery.

Dream sponge 

Just like Someone who try's to suck the life out of you... except they try to suck up all the excitiement, fun, positivity and passion from your dreams, and your goals in life.

They are usually sad and unhappy people who are jealous and looking to drag other down with them..

dont let a dream sponge ruin your life
