I've become a part time Jamaican, having travelled there 7 times in the past 6 months. I've learned some patois conversing and texting with my friends, but mostly from references on the internet. I usually can find a translation for just about any patois I encounter. However, I have run across a posted conversation I have not been able to interprate. If someone here can help me, I would appreciate it. It goes like this:
he: Liar
she: wah me lie abt
he:mi nuh able, cah afford a light up from you

Can anyone translate this?
