The Daily Hurl Some Abuse At trump and his dumpsters.

[mongers]

I'm not sure if this English word* travels well, but I feel it's rather fitting:

donald trump is without doubt the biggest Wanker* on the planet.

[Norgy]

I think British film industry and the TV series "The Inbetweeners" made "wanker" fairly understandable for most of us.

I'd like to add bell-end to the mix.

[Syt]

Yeah, wanker, bell-end, knob, are fairly well known by now, I'd assume.

[HVC]

They're known here, by native speakers at least, but people would look at you weird if you used them in casual conversation.

That's because they're bell-ends.

It is always a bit of a weird cringe moment when you hear foreigners trying too hard with such words. Even delivered with perfectly fine pronunciation at a time which text book works...it often sounds off.
It's a curious phenomena

I have to retire "clunge" and bell-end now? Dammit.
