I am writing a column for publication in a widely circulated newspaper, and would like to use a phrase meaning something like "call bullshit". I can't think of one that captures the meaning so succinctly. I certainly don't want to use the original phrase (not my style, and it's partly aimed at school students of varying ages).
To aid in finding options, the intended excerpt is something like:
If you claim to have compiled such a list then I know I can always call bullshit by finding an item you missed.
NB: the deception was not intentional on the part of the list compiler — they missed an item, not omitted it.
