Drunken Fumble

Drunken Fumble (or Drunken Fumbling) is a term for sexual encounters (though not actual sex) that happen while very drunk to the point where motor skills are limited, hence "Fumble".

Often a cause of awkward moments the morning after if occurring between friends, though occasionally turning them into a "full on" relationship.

Also a possible trigger for realisation of a different sexuality or experimentation if upon waking one feels it felt better than with their normal gender of preference.
