Jenny: Sure! (smiles)
Brad: Wow, that is a nice vagoo.
Jenny: I get that a lot. Thank you.
Mistakenly credited to 'Least I Could Do', but actually first showed up in the pages of a Fate/Stay Night doujinshi years before the webcomic used the term.
Since the original doujinshi censored the word "vagina", it showed up as vag followed by several OOOs.
Vagoo is commonly used on a popular image board, in such phrases as "GODZILLA DEMANDS VAGOO" or "GHANDI DEMANDS VAGOO".
Vagoo refers to the vagina and also the substance in the vagina. ei; 'Augh dude she pulled it out and it was all covered in vagoo'.
