喷

spray
💦 口 (mouth) + 賁 (burst forth) = mouth bursting out water = spurt
The 口 radical on the left marks a mouth or opening, and 賁 (bēn, to gush/burst forth) supplies both the sound and the sense. Together: liquid bursting out of an opening — spray, spout, sprinkle. Sounds close to pēn = pen-spray.
喷 — mouth radical 口 + 贲 (bēn, phonetic)
喷 is a semantic-phonetic compound. The mouth radical 口 signals the meaning—an action involving the mouth—while 贲 (bēn) supplies the sound, shifted to pēn. It originally described forcefully spurting or spraying something out of the mouth, and now extends to any spurting, gushing, or spraying.
