pointless condom
A condom (new or used), a condom wrapper, or some other evidence of a condom is present, but someone has still ejaculated inside a girl or otherwise engaged in behaviour that completely defeats the purpose and thus renders the condom pointless. e.g. Danbooru post #23768.
Note that this tag is for human carelessness or recklessness, not condoms that have broken accidentally. The tags can overlap when someone sabotages a condom, e.g. Danbooru post #590912.
