"Celulitious" is not a widely recognized term in English; however, it appears to be a variation or a misspelling of "cellulitis," which is a bacterial skin infection causing redness, swelling, and pain. If you meant "cellulite," it refers to the dimpled appearance of skin, often on the thighs and buttocks, caused by fat deposits beneath the skin. If you have a specific context in mind, please clarify for a more accurate response.
