Noticing in some of my posts. I usually fall back with grammatical phrases.
For example:
For (example, instance)
Usually
(insert odds here) likely
because
The notorious "Whatever"
mild cursing which masks more potent cursing (when speaking, it's a more intense case. I pretty much never curse in front of anyone; even people I am merely associated with, and especially strangers. Hell, even in confrontation, I resist cursing)
And on that note, "Heck/Hell, (statement)"
Simply put (or phrases to that effect)
To put it this way; my fallbacks are anything that makes me sound smarter. Even stupid things.
In regards to names. The best I'll remember is a title (like forum names), real names, I don't even bother learning; my memory in that area is short term at the most. If anything, name memory is based on how well I know someone, or how long I've known them.
And as for the GD curse. Being Catholic; I take offense to the term, and am not willing at all to say it/fall back to it. Yet, sci-fi slang versions like Firefly's term "Gorram" is a slightly different case. In context, it's still rather offensive; however, as minor justification, not many people are familiar with the term; and it's TV slang. I guess, the only reason I accept that more than the actual term is that it's from a TV show, rather than being a full-on curse (highest degree, while at that). Excuse my "zealotry" in regards to that. Just seeing GD made me think of making that known.
