I asked him what the heck that meant. He said picking up girls, what do they say in America?
I said "cruisin' for babes", and we all laughed.
Verb objects (and transitive/intransitive) are another difference between the dialects. In AmE you can say “I wrote Grandma yesterday”; in BrE that would be “I wrote to Grandma yesterday”.
A lot of AmE usage is becoming commonplace in Britain thanks to the Internet, though. You’ll now see commercials in Britain that implore you to “Search ‘Fred Insurance’ for full details”. Five years ago that would have been “Search _for_ ‘Fred Insurance’”.
My girlfriend and I were watching the Harry Potter movie cast reunion, and I noticed how the younger cast members let a lot of Valley-Girl-isms slip into their speech. "So I was like" (introducing a quotation), and "totally" (meaning very, extremely), and so forth. Quite different from how I expect a British person to talk. The younger generation of Brits seem to have fully embraced what Stephen Fry called "Buffy talk, Sabrina the Teenage Witch talk" and "the language of the Sunny Delight generation": https://youtu.be/xs5fH1ECzWc (Note that Fry was specifically addressing the related phenomenon of AQI, a.k.a. "uptalk", but he diverts into things like "I was like" to introduce a quotation.)
But in many forms of commercials it's advantageous to have a short text: you can use a bigger font while paying for the same size advertisement / poster / pop-up window. So maybe that was more a "shortism" than an Americanism.
