a guy/girl who is in a relationship but goes and messes around with another person and either kisses or fucks instead of you. for example a guy is dating a girl and then he is with her for 2 months but then decides to go have sex with a random girl from a one night stand instead of his girlfriend is a CHEATER.
omg he is such a cheater, i heard he slept with another girl and not his girlfriend.
such a shame. guys aint shit
