Bastard Variable

A variable that usually created on accident without knowing that it was created until it comes back and becomes completely out of your control. Like a bastard child.

Nick didn't realize that punching that llama would become a bastard variable and come back on him in a major way.

Whore Variable 

A variable that you use and redefine throughout the code without printing it out.

arr = input('Enter your array: ');
r,c = size(arr);
for j = 1:c

sum = 0;

for i = 1:r

sum = sum + arr(i,j);

end

arr2(j) = sum;
end
disp(arr2);

Oh man! That "sum" variable is a WHORE VARIABLE!
