Barbarian: Florida Man subclass
New Ability:
Hold My Beer
Outside of combat, you attempt one STR, DEX, or CON related task that a humanoid could theoretically accomplish without magic. Treat the attempt as DC 20 and make the roll at disadvantage.
Failure causes you 1d12 damage.
However, if you succeed everyone present (enemies included) is impressed and your Charisma based checks against them are at advantage during the next three situations you encounter them.
