George Zimmerman, the man acquitted in the shooting death of unarmed Florida teen Trayvon Martin, has apparently perfected the art of tough guy tweeting.

The killer-cum-Twitter troll on Thursday threatened someone by raising the specter of Trayvon Martin’s death and insulting the slain teenager in the process.

“I’m sorry I’m a day late for your slapping,” someone tweeted at Zimmerman with a meme labeled “It’s slap-an-idiot Wednesday.”

“We all know how it ended for the last moron that hit me. Give it a whirl cupcake,” Zimmerman responded.
