jawp

Rosmer sprang i' the saut sea out, 110 And jawp'd it up i' the sky; But whan he cam till the castell in, Nae Svanè lyle could he spy.

The Boistart Loch, again, as ye'll observe, lies atween twa hills; and when the wind blaws frae the east or the wast, it gathers into great gusts i' the glen, and maks the water jaw, and jawp, and foam like a caldron; and for this reason it has been ca'ed Boistart, or Boisterous, Loch.

Jawp, to throw water upon a person, to bespatter.
