Does it make sense?

So on Sunday I (21M, 5’7) weighed in at 132.6 lbs. Today on Wednesday morning I weighed 137.4 lbs. 132 on Sunday was really nice, my end goal is 131, so I was very close. I went to a big party on my campus and on Sunday I ate approximately 4700 calories on a binge. After Sunday I have been back in the gym 3 hours a day and been eating approximately 700 calories a day. Is this massive weight gain of nearly 5 pounds possible and will it go away soon? Or did I just supremely fuck up after 1 day of indulgence?
