Someone who is two-faced. A real piece of shit who will benifit off others then throw everyone else under the bus.

Someone who tells you they are trying to benifit you while actively screwing you over.
Wow, Mark really pulled some janus shit by donating sand to the children's park and then putting broken glass in it .

janus is this type of person that promises something, yet never actually fulfills them. he would also constantly bet in areas (despite knowing he is not strong in that area) with money & he also borrows money constantly, almost never returning the amount in time.
