Roller coaster

a) Only within a line can a circle be shaped. The track is always linear (beginning towards end)...no matter how many loops one rolls through.

b) Coast; verb - "to skirt, to go around the sides, to go along the border"...few suggest rollercoasters to sideline the minds of many while tempting each off-center.

If one mentally (logic) and physically (reason) rolls; then one coasts the implicating line (if > then).

a device which is permanently fixed to a site

Aka a device (suggestion by another) which is permanently fixed (ones consent) to a site (ones perception)...imagine a suggestion so AMUSE-ing that within ones perceiving MENT it can be PARK-ed by consent?

loophole

Only within (w)hole can a loop be shaped by tempting a partial to hold beginning and end together, like for example mentally thinking in a circle (logic) or physically turning against one another (reason). The use of logic within reason represents a "loop the loop" establishing a "hole in one".

this is the most dumb conspiracy ive ever seen
