crismar

A religious verb meaning to anoint with chrism (holy oil), used specifically for the sacrament of confirmation in Catholic and Orthodox tradition.

• El obispo crismó a los jóvenes durante la confirmación. — The bishop anointed the young people with chrism during confirmation.
• Los fieles fueron crismados en la ceremonia. — The faithful were anointed with chrism in the ceremony.
• Es tradición crismar a los confirmandos en la frente. — It's traditional to anoint those being confirmed on the forehead with chrism.

This is specialized religious vocabulary — don't confuse the underlying noun crisma with the informal expression romperse la crisma, which comes from the same root but colloquially just means to bash one's head.

• expression romperse la crisma — Common colloquial expression meaning to hit or crack one's head; it derives from crisma, the holy oil applied to the forehead in baptism and confirmation, which became an informal synonym for "head."
