When you want to criticize or make fun of someone, you can use the phrase "rip on," but there are several synonyms you can use to add more variety and nuance to your language. For example, you could "mock," "tease," or "ridicule" someone instead of ripping on them. If you want to be more direct and confrontational, you could "call out" or "rebuke" someone for their behavior. However, if you want to be more subtle and passive-aggressive, you could "snipe at" or "take jabs at" someone instead of outright ripping on them. Using different synonyms can help you tailor your language to different situations and moods.
