A creature from the Roberts family in the Genus Micheal. The yellow bellied sack sucker is a creature of the night. Found in dark alleys sucking only the dirtiest smelliest sacks. If you make eye contact with this creature you could vomit from its nastiness.
I was walking home last night from the bar when I saw it! “The yellow bellied sack sucker” was grunting and sucking so many sacks! It was terrible!
