No such thing as barm's or batches round here. It's a bap.
If the battery went flat on my phone it would have ran out of beans. "Couldn't call you earlier, got no beans in my phone"
Beans can also be used as an alternative for 'giving it some' or 'going hell for leather' "bloody hell dave, did you see that nutter on that motorbike giving it beans?"
And also as an alternative for semen. "shot my beans all over the bedsheets last night, misses wasn't impressed"
