What does snowballing mean?
Snowballing describes a process that begins modestly but then grows with increasing speed and momentum. The expression is commonly used for campaigns, movements, businesses, debates, and other developments: a local petition may snowball into a national campaign, or uncertainty about a product may snowball into a serious crisis. The image is vivid because a snowball becomes larger as it gathers snow while rolling downhill. In literal contexts, snowballing can also mean throwing snowballs or taking part in a snowball fight. A separate colloquial sexual meaning refers to ejaculation during anal intercourse. This explicit sense is much less broadly used than the figurative verb and is generally suitable only where the relevant vocabulary is appropriate. The figurative meaning can carry a slightly positive or neutral sense of enthusiastic expansion, though it may also describe problems escalating rapidly. It is related to the phrase “snowball effect,” which describes feedback that causes growth to accelerate.
To grow or develop rapidly, gaining size, importance, support, or momentum.
"Demand for the service snowballed after the company began offering free trials."
Often used when an initially small development becomes much larger through accumulating effects.
The activity of throwing snowballs, especially as a game or snowball fight.
"They spent the first half of the match snowballing behind the school."
Usually used in a literal or recreational context.
In colloquial sexual vocabulary, ejaculation during anal intercourse.
"The article uses an explicit slang term to describe consensual snowballing."
This sense is informal, explicitly sexual, and limited to contexts in which such terminology is appropriate.
Like a snowball rolling downhill, an initially small development can gather speed, mass, and momentum with astonishing speed.

Where does snowballing come from?
The word combines the Old English noun “snāw,” meaning snow, with the Germanic element “ball,” referring to a rounded mass. “Snowball” was already used for both a ball of snow and a large, steadily growing mass before the figurative verb “snowball” became established. The gerund “snowballing” developed from this verb and also came to denote the activity of throwing snowballs. Its modern figurative use follows the physical image of a snowball accumulating more snow as it rolls.
How snowballing is actually used
The figurative verb is common in formal and informal English and is especially associated with an initially modest development that becomes much larger. The snowball-throwing sense is literal. The sexual sense is informal, explicit, and restricted in register.
