I had a class today full of boys that love football, their grammar is pretty good but they lack any vocab, they clearly dont care about education at all and happily tell Welshy that they are being forced to repeat years and have been banned from x, y and Z classes.

Anyway we get on Ok-ish with them. For some reason today they all wanted to discuss their muscles and this involved me desperately trying to keep them on track as they wanted to arm wrestle.
Anyone one of them made a pretty unmistakable gesture and the other laughed in that kinda teenage boy way, and said that was why he had arm muscles.
So I whacked in "Wank" into Google translate and asked him if that was the reason.

Apparently he was miming going to the Gym.....
