Buttmogging is a term used in the femcel incelosphere and is used to mean that the buttmogger (peach-shaped) has better-looking buttocks than the buttmoggee (flat). Jennifer Lopez buttmogs other women all the time. At first glance, Nicki Minaj appears to be a buttmogger with a mean badonkadonk. But on closer inspection, her facial expressions while she sticks her hindquarters out makes it seem like her gluteal region is a projectile waiting to release a hazardous flatulence. Women from the Horner nation of Djibouti (transliterated from d’ya booty) are so great at buttmogging that the entire nation was named after their booties.
During an act of buttmogging, the buttmogger feels proud, whereas the buttmoggee feels humiliated.
