They'll sell them any arms in Texas.

I'm certainly feeling a little septic today- probably those prawns I had last night. I'm sure they're not supposed to be green......and I don't THINK they normally smell like that.............

You don't think he meant SCEPTIC, do you?
No...that would be silly.

No, he meant septic as in tanks---yanks.

'Sceptic' certainly didn't make much contextual sense either.
Not an ideal way, I'd have thought, to elicit a helpful response from our US friends........a bit along the lines of "oy, you sausage-eating Kraut bastard ! Whichen Vay to ze Hauptbanhof, and yer football team's shite, as well"?

Judging by the lack of responses from across the pond, you are indeed correct.

Of course, it may be that they didn't know rhyming slang had turned them into septics.

Thanks Bimmercat.
