I loooooooove spicy. I couldn't live without it! My favorites are:

1) tabasco
2) my homemade Mexican hot sauce that rivals King Taco and El Taurino in LA
3) tapatio
4) sambal
5) sriracha

Tabasco goes with everything. Tapatio goes with crab and anything Mexican. Sambal and Sriricha goes with Chinese and Thai. Sriracha is good with pizza too. What about you?
