What does "shiggering back" mean?

Hello, I've got a question about a word I never heard...I'm a musician from Italy, I was looking for a "laughing at" synonym whilst writing some lyrics, my south african friend suggested me "shiggering back at". Does it make sense? I'm used to write lyrics in British english because it's the type of english taught in Italy, and I never heard about shiggering back...Is it slang?
