Its nothing.

Its normal for a cooling system to be pressurized up to 15 PSI. If there is more pressure than that, the radiator cap will open and allow coolant to go to the overflow reservoir.

And I squeeze radiator hoses all the time. Usually its right before I take the radiator cap off. I do that to "feel" how much pressure is in there. I don't want to get burned or make a giant mess.
