The stuffed burrito is a sexual act that expands on the already well-known hot-carl. There are four steps involved in this particular act.
First, the man creating the stuffed burrito defecates in his partner's mouth. The feces is considered "the beans" of the burrito.
Generally, the receiver will vomit a little bit, creating a mixture similar to pico de gallo or other salsas.
Third, the performer rotates his anus away from his partner's mouth and sticks his penis into the poop.
Upon climaxing, he shoots his semen into the crap-filled orifice, supplying the burrito's sour cream.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume. The influencer in question, however, is unaware of the fan’s existence other than the general knowledge of having fans. Common examples include Dream and his stans. These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
