i was wondering if anyone could help name this technique or have practiced it

im gonna tie the question to a kick so bare with me...

you know how we have a staight kick, outside round house and inside round house??

we have a staight punch, outside roundhouse punch, is there an inside roundhouse punch?

kinda like a backfist action with fist but with a punch feeling??

any know if this or am i just playing aroun tomuch with my waza
