"Getting with" is a slang term commonly used to describe an intimate or sexual encounter between two people. However, there are several alternative phrases and synonyms that can be used instead. Some of these include "hooking up," "making out," "getting frisky," "having a fling," "having a one-night stand," and "getting intimate." It's important to remember that consent and communication are key factors in any romantic or sexual encounter, regardless of the terminology used. It's always best to make sure all parties involved are on the same page and comfortable with the level of intimacy being pursued.
