An acronym for "Holler If You Want Some" pronounced as hu - wis. Used to acknowledge an accomplishment, a good outcome/result, or even a possible good outcome/result. The use may sound somewhat different from when saying "holler if you want some" and "HIUWS".
HIUWS can also be used with the term "lezzz go" as in "HIUWS! Lezzz go" to enunciate the power of the accomplishment or outcome.
