It’s mostly neutral and practical. However, the overall message can sound flirty depending on the conversation.
For example:

- “lyk when you’re free tonight ❤️”
In those cases, the tone of the conversation makes it feel more romantic not the slang itself.
Is LYK Rude?
No, LYK is generally not rude.
It’s considered friendly and normal in casual texting. But in some situations, it may sound too short or lazy if the conversation is serious.
For example:

- Less appropriate: “lyk.” in a serious work discussion
Tone always matters online.
