An irrational fear of walking or of standing upright, sometimes also referring to fear of bases or basic things.
From Greek 'basis' (base or stepping) and '-phobia' (fear), literally meaning 'fear of the base or of standing.'
Basophobia is a genuine psychiatric condition, though rare—it's part of a family of movement-related fears that reveal how the brain can develop irrational terror of the most ordinary actions.
