Doom finger

The action of jabbing your thumbnail into another's arm. Depending on boniness of the finger and fingernail length, the doom finger can be VERY painful! Especially when done repeatedly. The user makes a fist with the thumb sticking out over the index, much like a knuckle sandwich but the thumb instead.

Jessica: *holds up doom finger*

Abby: *sees it and cowers*

Pointy finger of doom

This animation tactic is used in poorly dubbed Anime, especially those shows involving dueling or fighting. When a character extends their arm at full length towards their opponent(s) and then extends their index finger, this is known as giving the "pointy finger of doom". This is used in lou of the middle finger, or other originally written, but then dubbed trash talk.

Person 1: "Don't you hate it when they use the 'pointy finger of doom'?"
Person 2: "Why can't they just give the damn guy the finger like we do in real life?"
