Overusing one phrase repeatedly in writing. Mistake: Repeating “have sex” five times in one paragraph. Better: Rotate between synonyms based on tone.
Confusing romantic phrases with casual ones. Mistake: “We made love at the party last night” (too intimate for a casual retelling). Better: “We hooked up at the party last night.”
