look up any word, like thot:
 
1.
The alternate way to say Ke$ha (a female pop singer)'s name. This alternate name first appeared in the musical TV show, Glee. The school principle did not know how to properly say Ke$ha's name so he said, "Ke Dollar Sign Ha".
Did you hear the new song from Ke Dollar Sign Ha?!
Yeaaaa! it was awesome!
