To soak, to drench. A heavy fall of rain. Deluging; sweeping away by inundation. Applied to meat or drink that is thin, weak, flatulent, or viewed as debilitating to the stomach. To blash one's stomach, to drink too copiously of any weak and diluting liquor.--John Jamieson's Etymological Scottish Dictionary, 1808
On May-morning, the children go out into the country and fetch home the flowering branches of the white-thorn, or boughts of the narrow-leaved elm, which has just put forth its leaves, both of which are called "May." At a later hour, all the boys of the village sally forth with bucket, can, syringe, or other instrument, and avail themselves of a license which the season confers, to dip or well-night drown, without regard to person or circumstance, the passenger who has not the protection of "May" in his hat or button-hole. The sprig of the hawthorn or elm is probably held to be proof that the bearer has not failed to rise early to do the observance to a morn of May.--Rev. T. F. Thiselton-Dyer's British Popular Customs, 1876
"Persecute! Kill the nonbeliever!" Hey, any excuse to ostracize is a good one, right? ¬.¬
While I'm thinking of it, to all readers of this journal, I ask, as one who has only your best interests at heart: if your meat or drink is flatulent, don't partake of it. Just say no.
