Flipping Coins

Flip a coin, it has two sides
Heads or tails, they won’t collide
Place it square and flick your thumb
Many spins and then outcome

True or false, yes or no
May just be a friend or foe
Who goes first, who goes last
Three times slowly one time fast

Down it comes, back of hand
In the middle it should land
Take the score for what it’s worth
Raise your palm for dearth or mirth.
