A Gillespie is a moronic or vain individual who cannot take a joke or will never stop repeating the same joke. A Gillespie will often attempt to win praise from its peers with a self righteous flex (boast) about his personal life. A Gillespie has also most likely spent £40+ on vbucks and then has abandoned the account with said virtual currency.

A Gillespie is a reptilian creature with a severe desire for attention and admiration from its peers. It’s incredibly irritating and futile attempts often end with a being having a severe disliking of Gillespie’s on a whole.
