protuberant

His pursed up mouth made it clear that he was not a handsome man—the lower lip was heavy, somewhat protuberant.

He paced the length of the living room several times, his fists clenched, his protuberant lip grown heavier.

Ed did not touch the grass at any point except one: the point where his protuberant stomach most protruded.

He drew a sharp breath, which sounded through his yellow, protuberant teeth like a hiss.

His protuberant stomach swelled forth in the shape of a pear; his legs were small, but active and vigorous.
