"Keep you safe" or "stay safe" is an ambiguous and vaguely menacing phrase to keep people in line, a bit like when a gangster offers a business protection in return for a small fee. In order to stay safe, one must avoid things such as scientific fact, critical thinking, divergent opinions and basic civil rights. Instead, follow the soyence, and get all your misinformation fact checked. This phrase used to be known as "for your safety" or "for security purposes".
"We are installing cameras in all restrooms to keep our customers safe."
"In order to keep you safe, you must follow our guidelines and abandon independent thought."
"We want all our stakeholders to stay safe. That is why they will have to have microchip implants to accessbasic amenities. To keep you safe.'
people say this in order to inform someone to "kill them selves" without receiving any consequences from using the harsh term since both phrases are long for "KYS"
"bro this is to easy you're so shit"
"keep yourself safe dude"
Keep Yourself Safe typically means "kill yourself", as both words have the acronym KYS. Very useful for filtered chats as you can wish death upon someone without moderation being up your ass.
