American English is just surrealist comedy to an English person
Jim puts on a clean shirt and a clean pair of pants before sliding on his running shoes and leaving the house. Jim walks outside in his underpants, oblivious to the fact of the thing, for: Jim has not put on his trousers.
Jim, at some point in the day, makes some kind of remark about his "fanny". Jim announces he has a Vagina.
Jim experiences aggravation (probably at being laughed at) and announces he is Mentally Ill, he has proclaimed that he is "Mad" about being laughed at. Well, that's understandable, Jim..
The events of the day have perturbed Jim so much that he has become Pissed, he insists that he is Completely Pissed when he walks home after the events of his day, unaware entirely that he is telling us that he's blind drunk.
Probably the most forgivable thing is when Jim declines both a [hate speech] and a [slightly longer version of the same hate speech] because he doesn't realize that his British friend is first offering him a cigarette and then suggesting they try the pork dumplings.
Thus it goes Every Single Day.
