Cumbust
To have performed sexually at such a profound level that the utilised orifice has caught fire due to friction.
This could be down to a number of factors:
1. Overly fricative appendage surfaces, e.g. a scaley penis
2. Use of a lube with an insufficient smoke point for the activity, e.g. high-velocity anal sex lubricated with Butter (176°C) rather than Ghee (250°C) that meets an emulsifier, e.g. 'Baby Gravy', thus overcoming a natural fire retardant, e.g. 'Fannybatter'
Example 1 is pure friction but usually occurs before Cum enters the picture so is not relevant to this analysis
Example 2 is the true Cumbust in that it is down to the complex chemical interations of these substances when extreme kinetic energy is applied to them
