look up any word, like trill:
 
1.
One who stabs and is known for stabbing, most likely a thugsta or gangsta or killa manilla, thus the word has an "a" at the end of it rather than the normal, non-slang suffix "er".
"Man, dat dey mudda fuckoi is now knownst as a mutha fuckin' stabba since he went and stapped dat fucka in his itty bitty chess"
