  • To expend wastefully; scatter extravagantly or improvidently; waste, as property by foolish outlay, or the powers of the mind by devotion to trivial pursuits.
  • Synonyms Dissipate, Dispel, Disperse, Scatter. These words are often interchangeable. Dissipate and dispel, however, properly apply to the dispersion of things that vanish and are not afterward collected; dissipate is the more energetic, and dispel is more often used figuratively: as, to dissipate vapor; to dissipate a fortune; to dispel doubt; to dispel uncertainty. Disperse and scatter are applied to things which may be again brought together: as, to scatter or disperse troops; or to things which are quite as real and tangible after scattering or dispersing as before: as, to gather up one's scattered wits.
  • To become scattered, dispersed, or diffused; come to an end or vanish through dispersion or diffusion.
  • To engage in extravagant, excessive, or dissolute pleasures; be loose in conduct.
