Slang from South West England, a squitter is a thoroughly nasty, smelly, disgusting squirt of liquid or semi-liquid faecal matter. Usually used as a plural, the squitters is an attack of diarrhoea brought on usually by overindulgence in alcoholic refreshment. Using squitter in the singular form means a single squirt of repulsive, stinking, watery shit and by extension a repulsive, stinking, watery shit of a person. In both cases the best thing to do is flush the toilet with plenty of disinfectant.
"Malcolm, you'renothing but a two-faced squitter!"
While a non sequitur is a comment which does not logically follow the preceding comment, and a pre-sequitur is a comment relating to something mentioned much earlier in a conversation, a post-sequitur follows something yet to be said.
Compared with non sequiturs and pre-sequiturs, genuine post-sequiturs are rare, as most Americans find them immoral.
Jack: Hey there, sweet thang.
Jan: Sure, I'd love to.
Jack: Would you like to go out for a drink? Wait, what?
Jan: Hells yeah it was!
Jack: Was that some kind of post-sequitur?
Jan: Fine, have it your way. Toodle-oo!
Jack: Away with thee or I shall do mur-rer-der-r-r!
Terrible diarrhea that takes the form of a chunky, hot liquid gushing from your anus. May be caused by a horrific stomach bug, killer disease or vindaloo. Often accompanied by stomach cramps and a sinking feeling of hopelessness.
Not to be confused with explosive diarrhea which erupts with force, the squits are more of a steady trickle.
If you have the squits you will need to confine yourself to the toilet for at least 24 hours armed with a good supply of toilet paper, some Gatorade (for rehydration purposes) and some porno to stop yourself getting bored during the long shitting sessions.
Man: Hey Tony, where have you been for the last week?
Tony: Oh yeah, I came down with a terriblecase of the squits. My arse feels like a tattered sleeve from all the wiping.
