The shade
Heard in Tipperary
A euphemism for the area beneath an overhanging belly.
Begor willie if ya get any fatter, ya won't be able ta see yer micky, ah tommy as they say, not much will grow in the shade.
Good heavens, Willie, if you expand any further you shall no longer be able to behold your nether regions. Ah, Tommy, as they say, very little thrives within the shadows.
