"Derp" as used on this board is derogatory term for Deep State players. Someone like McCabe would be a classic "derp". The dictionary definition includes "foolishness or stupidity", which is how most here view the actions of the Deep State.
If you say something someone disgrees with they may accuse you of being a derp.
Our MIA co-host and chief instagator, the much missed Freeper "bagster" used the word "derp" with profligate abandon! I myself have been accused of being or acting like a "derp" by him several times.
Like you for instance.
Can a Derp also be a racist and an anti-semite?
Like you?
