Can have various meanings going from "faggot" to someone flat out spoiled, but is mainly used in the context of a "scene kid", or what others call a "poser".
When someone is fat, lazy and so full of flatulence their entire existence is substantially similar to a cow. And because a human has free will and is master of his/her domain, he/she transmogrifies into the cowmaster. The cowmaster is free to consume all things and contribute zero to society until he/she dies a gluttonous death.
"Look at that cowmaster! Holy crap!!! Sitting in a lawn chair, ice cream cone in one hand and slice of pizza in the other, watching as his wife uses a push mower to cut the front yard".
A person who has extreme knowledge of lore involving video games, books, TV shows, and more. Whenever someone messes up part of a lore, the loremaster will shame the person and attempt to educate them about the lore they got incorrect. The person will simply ignore the loremaster because he/she is annoying.

Mike: "I know, right? He's so annoying."
A device used to enhance feminine decollatage. Originally from Sweden and a favorite among celebrities, including Jennifer Lopez when she wore her infamous green scarf-dress, the loaster was introduced to a wider audience on an episode of Oprah's Favorite Things. One audience member had to be hosipitalized in the ensuing frenzy. The loaster is manufactured by Promessa Organic using a patented microfiber inspired by the silk of the Hobo spider Tegenaria agrestis.
