There's a pile-up of Britishisms here: arse (=AmE ass), Mummy (=AmE Mommy), footy (=AmE soccer--or whatever informal equivalent of soccer there is. Socky?). But the sore thumb sticking out here is bollocks (click link to see its Word of the Year discussion). Yes, bollocks sometimes--sometimes--is an equivalent to AmE bullshit in the sense of 'nonsense, (BrE) rubbish' But calling bullshit on (something/someone) is an American idiom, and you just can't stick new words (especially new words with not-quite-the-same-feel) into idioms. Kicking the pail is not the same as kicking the bucket; a bird in the hand is not worth two in the shrub, etc.
Who knows, maybe call bollocks on will catch on among the readers of the Daily News, and then we'll have yet another case where borrowing a word from one dialect to another brings a reduction in meaning and a change in usage with it. But I'm betting that British readers are hoping otherwise...
P.S. my arse! or my ass! also qualifies as an idiom, but the two dialects share it, albeit with different forms of the word. (See the link at arse above for more of the arse–ass story.)
P.P.S. Yes, there are a few examples of it on the internets. In those cases, taking the US idiom and replacing 'bullshit' with 'bollocks'. But the facts that (a) Urban Dictionary hasn't noticed it, and (b) two Brits on Twitter pointed it out to me as a bad translation underscore that it's a weird usage.
