Get the Masedmug. Mased is similar to based. Except the term mased is used to describe something you see but it depends on what it is.
Example 1:
P1:Awww look at those two people hugging. It's adorable:)
P2: Yeah that's pretty mased man.
Example 2:
P1: Oh my god, can you believe what Becky just did? What a bitch!
P2: Yeah that's pretty mased if you ask me
Example 3:
P1: I hate my school. My teachers. My classmates. They can't understand me!!! Y'know what will teach them?! My dads AK.
P2: Don't do it man, it isn't worth it.
P1: But...yeah. You're right. It would be mased of me to do that.

Get the Masedmug. When you put a motherboard in a case without standoffs, and then turn it on and wonder why the whole damn thing catches on fire, you have officially mased your motherboard.
