Gives drugs to someone (often as doping in sports), or slang meaning stupid people.
From Dutch 'doop' meaning sauce or dip, originally used for stupefying drugs. Evolved to mean any drug, then foolish people, then the act of administering drugs.
The word 'dope' meaning 'excellent' emerged as opposite slang in African American communities—the same word went from negative (stupefying) to positive (cool), showing how slang constantly inverts meanings.
