Can you use "I digress" after you rant, even if it is an excess rant of the original topic?

Can you use "I digress" after you rant, even if it is an excess rant of the original topic?

Example:

Person 1:
I got banned from league of legends
Person 2:
ok
Person 1:
Evan you're really making me angry. I hate you
Others: 
talking for a while
Person 1:
"I was getting tag teamed by a circle jerk duo who both lost lane by themselves
If I can't type back to those scum f*ck degenerates league can kindly screw off I digress

My friends and I are arguing if this is a valid use of "I digress" (excluding wrong grammar). Thank you.
