The three Weeblos were good friends.
They bought the video, Ureathra Chronicles, by blink 182.
Upon watching it, they decided that the many children in the video were weeblos, as in tiny people.
They later decided that Weeblos was a good name for the people that wanna blow blink. Weeblo, weebloblink.
They adapted the name and have decided to be weeblo sisters for the rest of their lives. In the hope that one day, they will Blow Blink.
