what is the name of this trap?

Opponent is black and does ..Ng4  and does ..h5  and doesn't castle. And i've castled king side. And he is willing to try to get me to take his knight, to weaken my pawn structure clearly a path for himself down the H column , keeping his rook in that H column. And setting himself up to cehckmate me with his Queen and rook down that H column. That's what it seems like it's an attempt to do.

In case "A"  an opponent did it to me

In case "B"  an opponent it seems to me tried it but I didn't take the bate.
