When he's saltier than a Pringle:
~ He's a little shit.
~ He'll avoid you until you corner him.
~ He'll be a little shit to whoever flirted with you, making them do stupid chores.
When he's angry:
~ He'll make sure whoever flirted with you will pay for what they had done.
~ Kiss you fiercely in front of the boys.
~Mark his territory by kissing you senseless.
~ Be overprotective, as in threatening those who looked at you in the wrong way .
But if he's all together:
He will make sure whoever flirted with you would pay dearly, no one touched what was his, no one. He knew you could take care of yourself but still, he would protect you until the day you died. Which would be never.
