Fat Bastard Auto has a bold, modern hybrid profile that can combine sweet fruit and citrus with earthy kush, spice and a noticeable gassy edge. The aroma is rich rather than delicate, with sweeter notes giving way to a deeper, more pungent finish.

The experience is commonly described as strong and euphoric before becoming progressively more relaxing. It can begin with an upbeat mental shift, while the body side tends to build gradually into a calmer, heavier-feeling finish.
