A.k.a. "mustache". Refers to where you are imbibing Pure Leaf tea or other liquid-libation which contains yucky dregs that you'd just as soon not hafta gag down while quenching your thirst, and so you angle your head back and slowly pour the beverage onto your mustache so that your Fu Manchu bristles catch most of the drink's offending particulate while allowing the refreshing liquid part to seep down through your upper-lip caterpillar and into your open mouth. Depending on the quantity and concentration of said sludgy sediments, you may need to pause frequently to wipe off the accumulated residues from your 'stache with a paper towel, but this minor inconvenience is small potatoes compared to the acute tongue/throat discomfort of having to actually ingest said stringy/gelatinous goo along with your flavorful fluid!
