A sub genre of main stream hip hop in which rappers boast about their drug dealing or former drug dealing vocation in verses thus glorifying the drug trade. More often than not trap hop often makes references to the lucritave coke trade
Most trap hoppers are southern rappers, see Young Jeezy, T.I, Rick Ross. others that rap about the drug trade (some even before the genre was established) are The Notorious B.I.G, Ghost Face Killah, The Clipse (with their latest album) and so on. trap hoppers dont necescarilly rap about drug dealing all of the time but the majority of there music does make references to it.
examples of trap hop songs are
10 crack Commandments - The Notorious B.I.G.
Kilo - Ghostface Killah, Raekwon
Hustlin - Rick Ross
Thug Motivation 101 - Young Jeezy
trap hop is good rapping but it does set a bad example for impressionable youth by making the drug trade seeem like a viable occupation. trap hop is probably the reason suburban kids think they have to sell drugs to emulate rappers in the mainstream.
