(Verb) To perform extraordinarily well at any form of competitive activity in a given period of time. One may also rally on another person, implying that one is significantly better at said competitive activity than one's opponent. Rally may also simply be shortened to just "Ral". Rally may also be used in some cases to stand for the act of extremely rough sex.
Note: The placement of "straight" in front of rally, just further stresses your superiority in said competitive activity, or the roughness of said sexual act.
