Squirrelly .. squirrely is a state of mind that approaches when you have had too much coffee. It is characterized by this tingling feeling in the thighs and in the hands and a tendency to nervous reactions and uncertain anger. It is usually accompanied by 'sewer mouth', white tongue and impaired judgement as to' how fast is too fast'. It can also be caused by too much Pepsi .. (although those who drink Coke tend to be immune due to slower mental reaction times.)
Attacks of squirrely may occur in the wee hours after bouts of caffeine drinking and are sometimes found at the scene of snoring homicides.
So what is an overdose of Mountain Dew? ahhh they are similar .. but the overdose of mtn dew is accompanyed by anextraordinary tallness. This manifests itself best in that the shoelaces seem to get farther and farther away.
