A portable spatoon for tobacco spit. Since the spit is brown it is known as "mud" and you spit in a jug hence the term "mudjug"

typically an old bottle or plastic cup that contains someone's spit from either chewing tobacco or dip. but there needs to be a sufficient amount of mud in a jug in order for it to be classified as a "mud-jug."
Dude! you spilled the fucking mud-jug all over my living room carpet! how am I gonna explain that disgusting brown stain? ughhhh it smells like shit!
