tinder-block

like how writers block is not knowing what to write, tinder-block is not knowing what to say on Tinder

"Man I don't know what to say to this girl. I have tinder-block."

tinder block

A girl that makes you as hard as a cinder block, she is a tinder block.

(Example) I met this girl named Cindy on Tinder, she is a tinder block.
