Nothing, Zero, Nada... Used almostly when bragging about not paying for a service or something.
It can also be used as an insult for saying someone is broke.
eg 1. I no get shishi for my phone but MTN allow me make call.
eg 2. Emeka no get shishi for pocket.
On the verge of a breakthrough for several years to no avail
Guy you don almost hammer, pray to God say you no go skales up
