Guilty Pleasures - What do you abuse?

[rulib]

Today I went through and made suggestions threads for stuff that I feel like I abuse every round:
easily accessible industrial space armor,
space walking in just a winter coat,
using .00001u thermite to melt rwalls,
breathing all round on an emergency oxygen tank

Those were my basically every round guilty pleasures that I would gear up with inside the first minute, what about you guys?
