Tweak the nose is an idiomatic expression that means to make a playful gesture of lightly pinching or twisting someone's nose. If you're tired of using the same phrase over and over, there are several synonyms you can use to express the same sentiment. Some examples include tweaking the proboscis, tweaking the snout, tweaking the schnoz, tweaking the beak, or tweaking the nostrils. These alternatives are handy when you want to mix up your vocabulary or find a less cliche way to describe the gesture. Regardless of the phrasing, tweaking the nose is a playful way to show affection or playful teasing.
