What does sucking mean?
Sucking is most commonly the present participle of suck. It describes drawing liquid into the mouth, as when a child drinks from a bottle, and by extension creating suction or drawing in air, smoke, or another substance. In figurative use, "suck up to someone" means to flatter someone insincerely, while "suck someone in" can mean to deceive or ensnare them. The word also has a vulgar sexual sense, referring to oral stimulation, and can be used informally before a noun to convey contempt, as in "a sucking excuse." Across these uses, sucking presents the image of forceful inward movement: a mouth, an engine, or even a person drawing advantage from another. Because it shifts easily between literal physical action, idiom, and insult, it is unusually versatile. Dictionaries normally treat it as a verb form, noun, and attributive participial adjective, with its register changing sharply according to context.

Where does sucking come from?
The verb descends from Old English succan, meaning "to suck" or "draw milk," and ultimately from Proto-Germanic *sūganą. It has close relatives in Old Norse sūga, Dutch zuigen, and German saugen, while the modern -ing form follows the ordinary English pattern of forming present participles. The related English noun suction came through Latin suctionem, from suger(e), "to suck."
