"Dear me, I am soaking wet."
Translation:Mo chreach, tha mi bog fliuch.
It is not used as a general intensifier. It is usually used to intensify 'wet', because a bog (an English word of Gaelic origin) is wet and hence soft. Because bogs are 'abundant in water' it can also intensify 'abundant' (apparently) but rarely anything else. Here is what Mark (2003) says - I will format it properly when I get home.
