origins from "
roller blinds". Keeping out LOL or fun like
roller blinds keeps out the sun.
When a person is having his/her lollerblinds down, nothing seems funny. It could either be due to a bad day, or a lacking
sense of humor.
I really tried to make her laugh, but she
totally hard her lollerblinds down", "Wow, that joke really made her
pull up her lollerblinds!", "That guy have had his lollerblinds down for
the last couple of days"
