<human>: Condense the text into a few key points

Okay so I was just thinking of nice meaningful gifts for my parents and my FH's mother, when I realized I'm at a loss for what to do about his step father. First off technically his mother and this man are not married so he is just his mothers boyfriend...person...thing. BUT he is the father of my FH's little brother and they have been together for about 10 years. FH and him are not like "oh you're more like a father to me" close though. Confusing I know :/ 
But I really feel we should give him a gift too! He has always been so nice and sweet to me since day one of our relationship and he is pretty much a grandfather to our son, I love this guy he is just super badass. Him and FH are like buddies. 
SO the question is what the hell kind of gift could I give this man? Nothing too lovey dovey or fatherly you know? I'm at a loss!
<bot>: FH has "buddy like" relationship with his mothers boyfriend but we need a Gift idea for him when handing out parents of bride and groom gifts.
