Stay in your lane means " talk about or do shit you know and stay out of the business if you don't" I'm sorry if your dumb asses don't understand the meaning. An example would be us on RIU having a conversation about dating or maintaining a successful relationship with a significant other. You Sir would not be able to participate is said conversation and would need to "stay in your lane ". You know nothing about dating and you fail at maintaining any relationship beyond that with your dog...and you better not be fucking your dog !!!!!!!
