A Lynndsae is toxic. She will be very clingy, and will most likely not support you in a new friendship or relationship. She goes from friend to enemy quickly, and most likely enjoys spreading gossip.

Internet persona(s) who happens to follow you and you happen to follow them back and maintain communication with and have a mutual liking for eachother whether it be friendship wise, etc. (Mutuals if more than one mutual)

Lynndsae’s are friends. They are not the other definition. That definition was written while that writer was young and immature. Lynndsae’s are perfectly nice, good people.
