Someone who uses other people for personal gain may be described as a user, exploiter, manipulator, opportunist, or taker. Some terms are much harsher than others, so it helps to describe the specific behavior rather than automatically assigning a strong label.
Which Term Fits the Behavior?
- Takes advantage of people: User
- Benefits unfairly from others: Exploiter
- Controls people to get what they want: Manipulator
- Uses circumstances or relationships for advantage: Opportunist
User
An informal noun for someone who forms or maintains relationships mainly for what they can get from others.
Example: “I eventually realized he was a user who only called when he needed something.”
Exploiter
Stronger and more formal. It suggests taking unfair advantage of another person’s work, vulnerability, or resources.
Example: “The scheme allowed exploiters to profit from people in financial difficulty.”
Manipulator
Best when the person influences or pressures others in a calculated way to get a desired outcome.
Example: “She felt he was manipulating her into taking responsibility for his mistakes.”
Opportunist
Someone who takes advantage of situations for personal benefit, sometimes without much concern for principle or loyalty.
Example: “He was seen as an opportunist who changed sides whenever it benefited him.”
Taker
An informal contrast with “giver,” describing someone who receives help, attention, or resources but rarely reciprocates.
Example: “Their friendship felt one-sided because he was always the taker.”
Freeloader
Informal and negative. It usually means someone who repeatedly benefits from other people’s money, food, housing, or effort without contributing.
Example: “His roommates were tired of him freeloading and never paying his share.”
Social climber
Specific to someone who uses relationships or social connections to improve status or gain access.
Example: “She accused him of being a social climber who only befriended influential people.”
Self-serving person
A broad description for someone whose actions are primarily designed to benefit themselves.
Example: “The apology sounded self-serving rather than sincere.”
Transactional friend
A useful phrase for a friendship that seems based mainly on favors, access, or exchange rather than genuine connection.
Example: “It began to feel like a transactional friendship because every conversation ended with a request.”
Parasite
A very harsh metaphor for someone who lives off others or continually takes without giving back. Use with care.
Example: “Calling someone a parasite is much stronger than saying they take advantage of people.”
Describe the Behavior When Possible
If you are talking about a real person, it is often clearer to say “They only contact me when they need something” than to rely on a broad label such as “manipulator.”
User vs. Manipulator
A user takes advantage of people for benefit. A manipulator specifically tries to influence or control people to produce the outcome they want.
