A situation which threatens life, limb, or sanity. Often sought by adrenaline junkies and avoided by unadventurous mundanes and induhviduals, though the latter two sometimes put themselves in danger out of their own stupidity, and not out of any well-informed decision on their part. Midterms are dangerous because they threaten your sanity. Relationships can be dangerous as well. If you're really unlucky, you might loose an arm or two as well as your mind in a bad relationship. Life-threatening things include college and driving cars. Danger is sometimes denoted by a warning sign.
