Answer:
Teens these days are trying to get a lot of attention from their peers. They feel overflowed with joy when they get liked or have more likes or followers than their friend or other people! I don't really know why, but its just that the human mind works that way. Whenever youre more "popular" or get more attention than others you feel superior than others.
Hope this helps!
