Use when an activity becomes suddenly popular and many people start joining it.

Popularity Surge

Can imply a lack of originality, as one is joining something already widely accepted.

Not Original

Highlights behavior influenced by group dynamics rather than personal preference.

Indicates supporting something mainly for personal gain, not necessarily for belief in the cause.

May convey skepticism if someone thinks the supporter has insincere motives.

Used in contexts where public opinion rapidly changes, often seen in politics and consumer trends.
