1) Anyone who watches MMA (such as UFC) and believes they know everything about fighting in the ring and/or on the street, but in reality would die in a fight scenario. 2) Someone who does not belong to any fighting discipline or take MMA classes, but still buys MMA memorabilia (such as TAPOUT shirts).
1) Justin: Oh man I could take that guy in a fight anyday. I'll just take him to ground and put him in an armbar!" Tyler: "Yeah, no, you're just a mixed martial asshole." 2) Ryland: "Check out my TAPOUT shirt!" Daniel: "Do you take MMA classes?" Ryland: "Nope." Daniel: "Then GTFO you mixed martial asshole."
