noun
Meaning belly hanging out from under a shirt.
Often seen on African and American men and, in even more upsetting cases, women. Think people of Wal-Mart.
The origin of "boep" (pronounced like "boop" but with a short "oo" as in "look") is from Afrikaans, a language related to Dutch, spoken in Southern Africa; meaning belly, like in beer belly. In South Africa, Afrikaans has been influenced by the multicultural population and thus this collision of languages provided an opportunity for a neologism, albeit under unfortunate circumstances.
Underboep is thus related to underboob, but not nearly as appealing.
