"He/She looks good but looks like your uncle, haha."
This is a playful and slightly rude comment. It implies that the person in question may be attractive, but they also resemble the speaker's uncle.
The "jajaja" at the end indicates that the speaker is trying to lighten the tone and make it clear that it's meant to be a joke. However, depending on the context and the relationship between the speaker and the listener, it could be perceived as offensive or inappropriate.
Here's a breakdown of the phrase:
* Se ve bien: He/She looks good.
* Pero: But
* Parece: Looks like
* Tu tío: Your uncle
* Jajaja: Haha
It's important to understand the cultural context and the relationship between the speaker and the listener when interpreting such phrases. What might be considered a harmless joke between friends could be seen as offensive in other situations.
