Boke is commonly used in Northern
Ireland slang to replace the verb "vomit", which can be the result to feeling physically or mentally ill. More times than others it is not physically seen.
Ahontus is derived from the Virginia Indian
chief's daughter Pocahontas, a delightful young
woman who was especially intune with Mother Nature, animals and Willow Trees.
Therefore a "boke-ahontus" implies a person who can not control their mother nature calling to want to vomit A LOT.
