look up any word, like donkey punch:
Merrikat is the shipping of Jack Barakat and Zack Merrick (of All Time Low). Jack has joked that "Jack" is an alternate to Merrikat, because Jack + Zack = Jack (or Zack).
"It was so cute when Zack carried Jack around stage."
"I know. Merrikat is so adorable."

The nickname given to the FICTIONAL couple Jack Barakat and Zack Merrick from All Time Low. It is purely fake...we think.
