Shadowing 

Manipulation of the algorithm of Tiktok by a group, to catch the attention of a popular content creator and forcing other comments to the bottom (into the shadows). This is accomplished by having all group members use the same emblem or avatar and liking each other comments to trick the algorithm into placing these "popular" comments ahead of others. Specific emoticons are also used in the same formation in the comments to increase visibility. The contents of the comments are usually irrelevant, but the number of comments will push out all non-group members and create the illusion that all the fans of that content creator are from that group.

We are going to be shadowing all his Tiktoks and his lives from now on.

1. The ability to predict one's future sexual endeavors by examining set individual's creases near the head of the penis.

Those who have been circumcised have lost this ability.

2. When a male is dancing with a girl and becomes hard in anticipation of a future sexual encounter

3. Dick wrinkles

Woah, these dick wrinkles are strong foreskin-shadowing.

His premature erection was foreskin-shadowing of things to come.
