adj. describing a hook-up that's suddenly (or not so suddenly) gotten very awkward. This doesn't have to be during the hook-up, it could become awkward after as well. Once the hook-up has been labeled a hookward experience we move to the noun definition.

noun: you label someone a hookward once they have become one through the process described above. Or when someone makes increasingly hookward advances that leave you feeling uncomfortable (and possibly creates an awkward tingling)

A casual invitation / threat used by an individual that is not afraid of fucking someone up.
