Still Sucks Thumb

Go To
His habit makes him stand out among royalties like a sore thumb.

Thumb-sucking is an Oral Fixation associated with babies. Normally, most children grow out of the habit. Some older children and adults however keep doing it, much to the embarrassment of others. In comedy this will be Played for Laughs to indicate that this person is a Manchild who never grew up. In drama this trope is used more to indicate a person's insecurity and/or to present him as cute and pitiful. Or that the character has fallen past the Despair Event Horizon.

Thumbsucking with adults is Truth in Television too, as some people still can't shake the habit off as they grow older, usually as a result of some trauma or feelings of stress, anxiety and/or insecurity. It may help them calm down.

Can sometimes be combined with Troubled Fetal Position. Contrast Finger-Suck Healing.
