Incorrect, when measuring voltage or impedance your multimeter is a high impedance load and will not draw any significant amount of current. It can safely be connected across any terminal you're likely to find in a home/auto setting.

If you're blowing fuses you've probably got the leads hooked up to measure current. When measuring current your meter is inline and is a low impedance source. If you connect it between the fuse in this case it will complete the circuit and now your meter is the fuse. This is not good for your meter or for the circuit.
