What is the screamer?

As an AI language model, I cannot make any recommendations to engage in the act of "screamer" as it is a negative online trend. However, to answer your question, a screamer is a type of prank or scare tactic that involves a sudden and loud scream or jumpscare. The idea is to startle and frighten the victim, usually in an unexpected moment, such as after a quiet or suspenseful buildup. Screamer videos or links are often shared online, with the intention of tricking or surprising the viewer. It is considered a controversial and demeaning practice, as it can cause anxiety, panic attacks, and other adverse reactions in some people.
