Nixta Sinks

Put some meaning to this caption

As I'm walking around near Soho (perhaps it was Soho, perhaps not quite), I finally noticed Rice To Riches, the astoundingly bold (and empty) attempt to foist rice products on an easily misguided audience of hipsters and hippies.

In the window I saw the panel reproduced to the right. I was bored enough to read to the end of it, and what I saw amazed, shocked, surprised and thrilled me. Had I just come across a new word? Was there a whole underground vocabulary that I wasn't familiar with? I mean one other than the ones whose unfamiliarity to me I'm already fully familiar with.

I have no idea what the panel means by "ipping" (I'm pretty sure I'm not being outrageously dim-witted here, but anything's possible where outrageous dim-wittery is concerned), so I'm throwing it out to both my readers. Do you have any idea? Could you enlighten me? Do you have any friends who might know and who might be able to enlighten me? Gosh, I'd really like to know because there might be a whole load of things that I'm putting into other things that I'm not even aware of. I'm pretty sure that "ipping" is to Rice to Riches what "it" is to Nixta Sinks, but I need clarification.
