The term 'GOOF-UPS' is a slang term used to describe a mistake or blunder. It is often used in the context of making a mistake in a task or activity. The term 'SNAFUS' is a similar term, also used to describe a mistake or blunder. It is derived from the military acronym SNAFU, which stands for 'Situation Normal: All F***ed Up'. Both terms are used to describe a situation where something has gone wrong due to an error or oversight.
