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"
