Out in the street, they call it merther

from Damian Marley – Welcome To Jamrock Lyrics on Rap Genius

Meaning

A line sampled from Ini Kamoze’s 6 track mini LP self-titled “Ini Kamoze” released on Island records label in 1984.

This lyric is commonly misheard as “murder” but is infact “merther”.
You can see the proof of this by listening to Ini Kamoze’s World A Music below, which is the whole premise of this song by Marley (it is sampled heavily). The line which you will here is

Out in the streets they call it merther, when riddims spacing out your head, world a reggae music on yah-eh

Thus clearly showing the correct lyric is merther, as correctly defined by user Jacky_Cox “Merther is the trance you experience when smoking cannabis while listening to reggae”.
