Shelley was standing right in front of me so I had to stonewall it by saying that Tarah was "delusional" just like they'd said about me at the trial.

While to stonewall conjures associations with the bar in New York that played a role in the gay rights movement as well as Confederate General Thomas J. "Stonewall" Jackson, this verb originates in the simple sense of obstruction conjured by a wall made of stone. The first recorded use of the verb form occurs in 1914.
