A verb from the Polish language, masturbating furiously in under five minutes. Pronounced gal-ert
Originated in the late 1990s in sub-zero environments where men would have to galert to be able to masturbate. Subsequently, men who could not achieve their goal in a very short period of time would almost certainly lose their penis to frostbite.
He went for a galert 4 minutes ago, he should hurry up or he'll risk losing it.
