A "doopy" describes someone who is mentally slow, silly, or simply stupid.
The reference indicates that a "doopy" person can be considered:
- Mentally slow
- Silly
- Stupid
This term is often used informally to describe someone acting in a foolish or unintelligent manner. For example, the reference provides the phrases "your dopey friends" and "a dopey TV show." These examples show that "dopey" (another spelling variation) is used to describe people and entertainment content that lack intelligence or are considered foolish.
