Matt Berry is best known as Laszlo Cravensworth in the television comedy What We Do in the Shadows, and this clip draws on that character's grand, old-fashioned confidence. Short spoken moments from the show circulate widely as reaction sounds because Berry's delivery is instantly recognisable even without the picture. Grifting 101 works as a shorthand title for a mock lesson, so editors reuse it whenever a video pretends to teach something shady with complete seriousness. Its appeal is that contrast: a formal lesson name attached to dishonest behaviour.
