For me it's underwear, wall hangings or pictures and tools.
Firstly, whoever invented the y-front cock-pocket is a knob and that's not a compliment, even in this context. Why anyone would bother navigating that maze rather than just pulling the things down is beyond me. The 2 dollar Neoprene Elastane sports jocks I buy might mean I am in trouble if I fall asleep in front of the heater but boy do they soak up the taint sweat.
Second, if you like the look of that thing so much, then hang it on your own wall and raise a toast to me while you look at it.
Lastly, that wonder tool company is running a late night ad for a reason. No one who is fully awake would consider buying it for a tradesman. Think the triangular saw-blade for example. I mean sure it can cut in a circle but maybe those 3 tiny points of contact means it won't last all that long and have a bigger chance of jambing and taking a limb off when it kicks back.
I'm partly joking here but mostly I'm not.
Art, clothes, and tools are good ones. Things that get used often when I'm alone, especially electronics or tools in the shop. I'm really more about not being surprised with things I'm expected to use when they're around, like using one set of painted plates when the parents visit because they got them for me years ago, or goofy holiday clothing. I'm ok with those things, but I want to have some say in picking it out.
Consumables like food and alcohol are mostly fine, but similar rules, and don't expect me to eat it in front of you right away just because you bought it. The "try it on" or "eat it now" pressure takes all the fun out of a gift for me too.
