Grumpa said the world in 50 years would be like The Matrix after we took him to see it.
A term often used by mainers when describing a large bowel movement. The people who use this term usually have a cigarette hanging from their lip and are fisting a bud. Also often used by construction workers and people who exhibit bad etiquette.
If there are any sorority girls present when this expression is used they surely will not understand. If for some strange reason they do, they will be disgusted.
