BAD IDEA
Can a referee give himself a red card?
No, referees can't red-card themselves — who would referee the referee?
A referee giving himself a red card is basically a leadership crisis on the pitch. Officially, referees hand out cards to players or coaches, not themselves. If a ref seriously messes up, it's other officials or governing bodies that handle the discipline, not a self-issued red card. So no, it doesn't happen, and if it did, it'd be the most confusing show ever.
