The act of pleasuring yourself in manure and/or horse dung.
Farmer to friend: Couldn't believe it, went down to clear out the muck-spreader, only to find a load of tissues and some bloke squibbing himself senseless.

While performing procreation in the canine position it is the act of skillfully and secretly sliding one’s thumb over the anus of the receiving partner and apply firm pressure to ensure a taught fit will occur and inform that person you are about to test the area. You then insert the tip, just the tip, of the thumb to stimulate/exonerate the gratification.
She was very happy when i decided to use the squibbing technique instead of railing the evil little hole so she would walk straight that week.
