A: How do I look in this yellow dress? Don’t you think it’s cute?

B: You look like a big, round lemon. It’s ugly.

A: What? You really have no filter.

B: I’m just being honest.

Note: If someone has no filter, they just say whatever comes into their heads. Literally, “no filter” describes pictures that have not been altered with any kind of filter or visual enhancement. “#nofilter” is a common hashtag on social media, especially the photo-sharing platform Instagram.
