Thank you Faldage, I'm sure Jackie is aware of this. I went on a trip after sock and socket and stumbled upon an blood chilling issue:

sockdolager
1830, "a decisive blow," fanciful formation from sock (v.) "hit hard;" also said to be a variant of doxology, on a notion of "finality." The meaning "something exceptional" is attested from 1838. Sockdologising was nearly the last word President Abraham Lincoln heard. During the performance of Tom Taylor's "Our American Cousin," assassin John Wilkes Booth (who knew the play well) waited for the line "Well, I guess I know enough to turn you inside out, you sockdologising old man-trap," and as the audience laughed, Booth fired the fatal shot.

Can you confirm this as a true story or is it a legend ?
