'Bodygasm' has a few meanings:
1. Often used by stoners or occasional weed smokers to describe the intense body high one gets from really good marijuana.
2. The rare and often sought-after intense, whole-body sensation that may occur after a masturbation session. It goes beyond the good feeling in the legs and hips alone.
3. Used infrequently to describe an intense body-high after using *any* narcotic drug or alcohol product.
