I was letting my friend drive my car and he accidentally backed up into one of those little driveway markers. The market went under the bumper and caused a bubble crack to form on the bumber.

It looks like spider webs and is about a pea sized bubble.

Anyone ever have anything like this happen? Any way I can fix this without going to the mechanic?

 

A. Kill your friend and take money for repairs.
B. I think you are going to have to paint it and blend if it really bothers you that much, otherwise if it's not too obvious, I would save the bucks and leave it be.
C. You might be able to go to an Autozone and get duplicolor touch up paint and give it a try......
