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
