tickles
Se ríe cuando le hacen cosquillas.
They laugh when they are tickled.
Pica si no rascas, y da cosquillas cuando lo haces.
It itches if you don't scratch, and it tickles when you do.
— Sympathy for Lady Vengeance (2005)
It tickles me.
Hazle cosquillas en el pie y verás cómo se levanta.
Tickle his foot and you'll see him get up.
