Duncan mighty shows off pounds note got friend

It seems like you're referring to a popular Nigerian song by Duncan Mighty, titled "Fake Love". In the song, Duncan Mighty sings about a friend who showed him a £100,000 note, which is a significant amount of money.

The lyrics go like this:

"Ah ah ah, my friend dey show me £100,000 Ah ah ah, my friend dey show me £100,000"

In the song, Duncan Mighty is expressing his surprise and admiration for his friend's wealth, as £100,000 is a substantial amount of money. The song is a reflection of the lavish lifestyle and material wealth that some people in Nigeria and other parts of Africa aspire to.

It's worth noting that the song is not meant to be taken literally, and the £100,000 note is likely a metaphor for the friend's wealth and success. The song is meant to be an expression of admiration and envy, rather than a literal representation of the friend's financial situation.
