Standard kanji spelling; 糞 is a strong vulgar prefix here.
Katakana spelling of the prefix, common in casual writing.
Mixed kana-kanji spelling, also seen.
Compound of 糞 (くそ, 'shit', a vulgar intensifier) and 力 (ちから, 'strength'), with rendaku voicing to ぢから. The exact origin is uncertain, but it follows a common pattern of using くそ as a pejorative or emphatic prefix.
