IFR 

Instrument Flight Rules

The Instrument Flight Rules (IFR) are a set of rules for flights where it can not be assumed that pilots will be able to navigate their aircraft or maintain separation from obstacles, terrain, and other aircraft by reference to features outside the cockpit.

All flights which take place in Instrument Meteorological Conditions (IMC) must be conducted in accordance with the Instrument Flight Rules (IFR). However, flight under the Instrument Flight Rules (IFR) may also be conducted under Visual Meteorological Conditions (VMC).

Looks like the weather forecast is predicting IMC over the airfield tomorrow. We better change our flight plan from VFR to IFR for tomorrow's flight.

iframes 

iframes is short for invincibility frames. In some video games, after taking damage you will be immune to damage for a short period of time afterward. This period of invincibility is called iframes.

You: How'd you run right over those spikes?
Friend: I had just taken damaged and used my iframes to run through.
