Young Teen Girl With A Sexy Whale Tail

Though the word is not included in major formal dictionaries, web-based user-generated dictionaries like the Urban Dictionary (which provides "pull me thong" as an alternative term for whale tail), the Double-Tongued Dictionary and the Wiktionary, have entries for the word. The book compilation of Urban Dictionary describes the whale tail as "the shape formed when a G-string rides up high over a woman's pants or skirt". The Dialect Society mentioned "longhorn" as an alternate term for the whale tail. A related term – sagging – implies the practice of wearing pants or shorts below the waist so as to reveal some or all of the wearer's underwear. Another related term – buttock cleavage – implies a minor exposure of the buttocks and the gluteal cleft between them not covered by an underwear. A third related term – Visible Panty Line (VPL) – implies underwear becoming visible through clothes.
Use of the term beyond fashion
The word of the year has other uses too, some in coinage even before the fashion connection. These uses encompass diverse areas like science (arterial branching, magnetization curvature), industrial design (photographic flash diffuser, bicycling saddles and helmets, power trowel handles, hydrofoils), art (sculptures, license plates), geography (beach formation), and one of the most popular automotive spoilers that spilled over into other vehicles as a fashion statement.
