Liability

In the most general sense, a liability is anything that is a hindrance, or puts individuals at a disadvantage. It can also be used as a slang term to describe someone that puts a team or group of which they are a member at a disadvantage, and would thus be better off without.
Accounting liability
In financial accounting, a liability is defined as an obligation of an entity arising from past transactions or events, the settlement of which may result in the transfer or use of assets, provision of services or other yielding of economic benefits in the future.
They embody a duty or responsibility to others that entails settlement by future transfer or use of assets, provision of services or other yielding of economic benefits, at a specified or determinable date, on occurrence of a specified event, or on demand; The duty or responsibility obligates the entity leaving it little or no discretion to avoid it; and the transaction or event obligating the entity has already occurred.
Liabilities in financial accounting need not be legally enforceable; but can be based on equitable obligations or constructive obligations. An equitable obligation is a duty based on ethical or moral considerations. A constructive obligation is an obligation that can be inferred from a set of facts in a particular situation as opposed to a contractually based obligation.

The accounting equation is the mathematical structure of the balance sheet.

Probably the most accepted accounting definition of liability is the one used by the International Accounting Standards Board (IASB). The following is a quotation from IFRS Framework:
