vt. to deceive or betray someone, especially by being unfaithful in a romantic relationship
adj. involving deceit or betrayal, especially in romantic contexts
The term "two-time" originated in the early 20th century, combining "two" (indicating duality) and "time" (an instance or occurrence). It metaphorically describes someone who engages in two simultaneous romantic relationships, effectively "doubling" their commitments deceitfully. The word reflects a colloquial yet vivid critique of infidelity, emphasizing the act of repeating betrayal.
