look up any word, like wyd:
 
1.
To have a very watery bowel movement that bursts out of ones anus uncontrollably, while making a noise similar to the noise heard when one squeezes a plastic bottle of Hersheys milk chocolate.

The shits; diarrhea.
I had to get up five times last night to walk Muffy, as she had the Hersheys again!
