A comical depiction of Crying or Tears.
A comedic teardrop is used when the tear is drawn on for comedic purposes, rather than to actually represent happiness/sadness/pain/pleasure/etc. They usually have a specific color, rather than being transparent like real tears, and are usually connected directly to the eyes. A teardrop may also accompany Yawning.
If the character appears to be actually crying, or the teardrop is transparent, it is usually not a teardrop. For all other instances of shedding tears that don't properly meet the requirements for teardrop, use Tears instead.
For non-comedic pictures with a single teardrop, use Single Tear.
