blind as a trump
Doing something stupid and self-destructive after being advised by many people not to. Refers to Donald Trump looking at the solar eclipse without eye protection.
Scientists: "make sure to not look directly at the sun, you should use proper eye protection."
Idiot: looks at sun, suffers eye damage "It hurts! I can't see anything! Whaaa"
Idiot's friend: "You're blind as a trump."
