A halfy is when a person gets as close to a complete orgasm as he/she can, and then gets distracted and/or turned off by his/her partner or something else, therefore losing the orgasm completely and is unable to regain it. The person has had "half" an orgasm, or a "halfy".
An example of a Halfy would be if a woman is climaxing and her boyfriend cums to soon,it could distracther from her own orgasm, even though it has already started, and she will lose it completely. She will only have felt the beginning of an orgasm and will be unsatisfied.
