Real name of happy birthday trap?

[Darth Brandon]

Does anyone know the real name of the "Happy Birthday Trap?" I like to build traps in reallife and want to learn how to make one like this, but i cant find it anywhere because i dont what to look for.

Someone asked this the other day and i couldnt find ANY similar to it except in other games. Nearest i could find was the "Whip Trap". But its like one stick that is bent back and tensed with a few spikes on it, ready to "Whip" around Horizontally into ur legs / chest, rather than Vertically into ur whole body lol.

I mean the happy birthday trap itself is feasible, but highly complicated and would need a lot of camouflage across its bed of spikes and probably unreliable IRL compared to the whip trap. Which only needs to be bent behind a large object / door / tree / etc. You could only see the tripwire, otherwise it was too late. xD
