お荷物 is a more colloquial and slightly softer term for a burden or dead weight, often used for a person who is a liability.
Compound of 厄介 (troublesome, burdensome) and 物 (thing, person). The exact historical derivation is uncertain, but the combination naturally yields the meaning 'troublesome thing/person'.
