Full Sigmund 

This is a variation of Full Send used by Twitch streamer AvoidingThePuddle. Someone in chat got autocorrected by their machine and sent a message that said Full Sigmund instead of Full Send, thus creating this term.
Mostly new people will ask during the break for it's meaning, self reporting that they're new and getting banned for being new since they don't know that questions aren't allowed.

"Last night on Carl, there were 2 survivors left on the stage and I went Full Sigmund on that other dude with my Afghani Rocket Launcher."

Full sigmund 

This means full send used by Twitch streamer AvoidingThePuddle a.k.a. Aris.

Orginally, it came from Aris switching screen to take a break, where the screen said "no signal". Someone in chat's autocorrect was stoned, so the chatter ended up typing no Sigmund, thus giving Aris the idea of setting a screen with "Full Sigmund" while playing a catchy tune during his break.

"I ordered Mexican AND Indian food yesterday and went Full Sigmund on my enchiladas and butter chicken dishes. It was sooo good."
