dojikko pose
Any pose where the character winks while sticking out their tongue and tapping themselves on the head. Often associated with utterances like "teehee" or similar.
If instead of tapping their head the character is holding their hand behind their head or making a 'V' sign, use the tehepero tag instead. If they're touching their head with both hands with both eyes closed, use ah eto... bleh (meme).
