It's a tape that has strong adhesive and a felt-like backer that you would tape over a blister or chafed spot in a boot or shoe. The adhesive is sweat proof, and the felt backer both pads the sore area and also prevents further sliding and rubbing that leads to chafing and more blisters.

"Full stack" is meant to be complimentary but is also highly situational, in the same way credentialed engineers and credentialed architects bristle when those.terms are used in the tech sector. They Did the Program, and Showed the Work. Those.of us in the tech sector are doing some stolen valor.by adopting those titles in our roles.
"Full stack" is situational because no two shops use the same stack. Every shop has its own technology preferences, so if you know Apache and ServiceNow, you'll still be useless in a shop that uses Xendesk and Nginx. It just.means you know YOUR venue's technology organization.
Really it's an industry buzz term, and you should run from any recruiters who casually use it but can't also describe exactly WHAT stack that shop they're pimping is using.
I understand most of the stack from photons to UX. I run optical, packet hardware and I define software. I consult on security and I inform the service desks. I'm that "break glass" guy you don't want to call in the middle if the night because I might be sarcastic, and then I'll cancel meetings for the next two days in revenge.
I've also been in this swamp since before the sky learned how to rain.
Call me whatever you want, but you'd best smile when you say it or I'll delete your account and blackhole your network.

Tight design that stays out of the way, and updates frequently.
