Morphology

butt + floss

The meaning is partially derivable: 'butt' (buttocks) combined with 'floss' (a thin thread) suggests a thin strip of material sitting between the buttocks, so learners who know both words can often infer the general idea. However, this is slang and metaphorical—the exact sense of a revealing swimsuit/underwear (a thong/string) and its humorous use as a noun may not be fully predictable without exposure, so it is not fully transparent.

Etymology

Butt floss is a joking name that mixes butt and floss: imagine a thin strip of cloth running between the buttocks like dental floss. That's why it means 'very revealing swimsuit or underwear'.
