Assuming you are a 3D model designer for online metaverse which uses 3D avatar. Since 3D avatar is 3D model, it does not have orgasmic anatomy, but 3D model looks like human. For avoiding confusion between orgasmic anatomy and part of 3D model, I'm going to give a specific name (3D model label) to specific body part wherein the specific name is different from anatomical name of human. 

Rules
1) Each name of the 3D model label will be combination of just 2 words. Which represents structure and/or function in consice manner. For example, I will give a name as "DNA sack" to testicle. 
2) Each name of the 3D model label should not use a word of human anatomy itself. For example, the label for testicle should NOT be "DNA testicle". For example, the word "mouth" should not be used for a label for mouth.

Request
Please give several ideas of name (3D model label) for mouth.  Use words with all capital letters to highlight key points, but make sure that words with all capital letters appear less than 12 times
