"What are you into?" is a question that can have different meanings depending on the context. Here are some possible interpretations:

• Asking about interests: In casual conversation, "What are you into?" is often used as a synonym for "What are you interested in?" or "What are your hobbies?". When someone asks you this, they want to know about your interests and things you enjoy doing.

• Asking about sexual preferences: In some contexts, "What are you into?" can be a way to ask about someones sexual interests or kinks. However, its important to note that this interpretation is not always appropriate and can be ambiguous or uncomfortable if not communicated clearly and unambiguously.

• Asking about recent activities: Another related colloquialism is "What are you up to?" which means "What have you been doing recently?".

• Asking for clarification: Sometimes, when someone asks "What are you into?" it elicits in turn the question "What do you mean?".

• Asking about general interests: "What are you into in general?" can mean "What are your passions?" or "What do you like?".

Its important to pay attention to the context and tone of the conversation to understand the intended meaning of the question.
