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.
