halifax special 

When you bone someone then shit in their bed and leave. A properly performed halifax special will leave the unsuspecting victim thinking they involuntarily released a steaming loaf while asleep.

The other day after scarfing a giant burrito I gave my ex a halifax special that was especially stank.
