Sure! The phrase "pooch out" is a verb that means to round or stick out your lips as if you are about to kiss someone. It can also imply making your lips look fuller or puffier.
In more advanced contexts, "pooch out" can also be used metaphorically to describe someone who is trying to show off or exaggerate a certain expression or emotion, especially in a playful or silly way.
"pooch" on its own can also refer to: 1. A dog (informal usage). 2. To be in a situation where something is not right or is out of order (like "to pooch things up").
While "pooch out" is quite specific, you might come across idioms or phrases that involve lips or kissing, such as: - "Pucker up": This means to get ready to kiss. - "Lip service": This means to express support or agreement without really meaning it.
So, "pooch out" is about making your lips round and sticking them out, often playfully or for a photo.
