A meme from 4chan, which refers to a feminine male who is indistinguishable from a female, hence a trap. They often crossdress to make their appearance more convincing. As a rule of thumb, if you can correctly tell the gender with complete certainty from the thumbnail alone, it's not a trap. Posts containing a trap do not need the male tag unless there are other male characters present. However, shota may apply if the trap in question is a child.

Reverse trap refers to the opposite of this tag.
