Why this word is great
INTERLOPE — [Verb] To intrude or meddle in the affairs of others, especially for personal gain. Likely a back-formation from 'interloper' (late 16th century), itself from 'inter-' ("between, among") + '-loper' (possibly from Middle Dutch 'loopen', "to run"), thus literally "to run between." Unlike "interfere," which implies general obstruction, or "trespass," which denotes physical encroachment, to interlope is to make an unwarranted, self-serving incursion into a guarded sphere—a commercial monopoly, a private conversation, a closed society. It is the rival trader slipping past the East India Company’s blockade, the social climber angling for an introduction in a private salon, the faint static of a third party on a poorly secured line—a quiet crime of opportunity, perpetrated in the spaces between jurisdictions where the rules assume you do not belong.
